Data Grid Laravel

Data grid package used to build advanced grids with a matching front-end package.

Allows for searching, filtering, paging & some other advanced features.

Installation

You can install the package via composer:

Please also note that a companion front-end package is required to use this package to it's fullest:

Info

The primary responsibility of this package is to provide an easily understandable development path to create simple or advanced data grids. Although this package can be used in a standalone fashion it is recommended to be used with its companion front-end package data-grid-vue. This front-end package provides all the necessary tools for rendering data grids on your front-end including making use of all the simple and advanced features as provided by this package.

Usage

Package usage can be split up into multiple sections. All will be discussed below:

Initial setup

Some initial setup is required. Most notably running the included migration of this package.

Migrations

You can publish and run the migrations with:

Creating a data grid

Data grids can be created by using DataGrid facade in any php class as required. The following is a simple example of a data grid. An in-depth explanation follows:

The example above shows the simplest form op setting up a data grid. Data grids consist of mainly 2 aspects:

• Query used for the data itself
• Various properties to build the data grid

Query

This query will be used to gather and display any data that is actually required in the data grid. The query can be any laravel based query using Models, the DB facade or relationships. It is however important to note that the expected type is Illuminate\Database\Eloquent\Builder. This is prevalent in the example when using the query() helper on the User model. Also note that any relationship access should be handled with join() and leftJoin() manually.

Properties

Lastly we look at data grid properties. The DataGrid facade make a large amount of properties available to the developer for use. In the above example the addColumn() property is used. As its name suggests, it adds a column to the data grid. There are however many properties to use. From adding a simple column, to adding advanced columns, specifying data grid settings to setting up pre-defined data grid views. All these will be covered and thoroughly explained.

Finalizing your data grid

After specifying any and all properties as required, the get() function can be called on the data grid instance to get a neatly formatted keyed array with the data grid items and meta data. This array can be passed to your front-end for usage with data-grid-vue to render a data grid. However, if used in a standalone fashion this array can also be used in any way as required by the developer. The "items" key contains the actual items to be rendered in the data grid. The "metaData" key contains all required settings passed to the data grid. See an example below:

Data grid properties

The following section will explain every property available on the data grid instance.

forQuery()

Also, as mentioned above the forQuery() function is used to pass the actual data query to the data grid.

setQuery()

The setQuery() function can be used to set the query of the data grid.

setRequest()

The setRequest() function can be used to set the current request.

setPage()

The setPage() function can be used to set the current page number.

defaultOrderBy()

The defaultOrderBy() function is used to pass default orders to the table. These apply by default if no user input exists.

setColumns()

The setColumns() function can be used to set the data grid columns. Note though, that this method should be avoided if possible. Data grid columns should be set using the built in addColumn(), addAdvancedColumn(), addIconColumn() and addFileColumn() functions.

filterWithConfig()

The filterWithConfig() function is used to apply the setting that forces the data grid to use the persistent configuration to apply and consume filters. This allows data grid filters to persist even after closing the app.

searchWithSession()

The searchWithSession() function is used to apply the setting that forces the data grid to use session storage when searching instead of route parameters.

sortWithSession()

The sortWithSession() function is used to apply the setting that forces the data grid to use session storage when sorting instead of route parameters.

pageWithSession()

The pageWithSession() function is used to apply the setting that forces the data grid to use session storage when paging instead of route parameters.

addColumn()

The addColumn() function is used to add a column to the data grid. This function takes a few parameters to set up the column correctly. These are covered below:

addColumn(value, label, type, searchable, sortable, hidden)

The value parameter indicates the DB column value. Important note, when using joins in your query. Values must be prefixes with table names.

The label parameter indicates the actual label used for the column on the front-end.

The type parameter indicate the type the column takes on. Types are used by the data grid to apply search terms and filters. There is only a set amount of filters available. these will be listed and explained at a later stage.

The searchable parameter indicates whether to make this column available for searching.

The sortable parameter indicates whether to make this column available for sorting.

The hidden parameter is used to indicate if the column is hidden by default.

addCustomColumn()

The addCustomColumn() function is used to add a non-searchable and non-sortable column to your data-grid that doesn't match a valid select statement. This function is intended for custom column that are mutated on the front-end using slots. The function takes a identifier parameter for the slot alias and a label parameter for the column label.

addAdvancedColumn()

The addAdvancedColumn() function is also used to add a column to the data grid. This function however takes a callback function of type ColumnDefinition. ColumnDefinition can be used for fine grain control over columns and for applying advanced functionality. Definitions will be covered at a later stage in full detail. An example is listed below:

addIconColumn()

The addIconColumn(), as the name suggests, can be used to add a column to the data grid that only displays an icon. This function also take a series of parameters. These are covered below:

addIconColumn(value, label, icon, color, searchable, sortable, hidden)

The value parameter indicates the DB column value. Important note, when using joins in your query. Values must be prefixes with table names.

The label parameter indicates the actual label used for the column on the front-end.

The icon parameter take either a string or callback function depending on the column requirements. When passing an icon as a string. That icon will be used in all cases. When passing a callback function it must be of type IconDefinition. IconDefinition is used for fine grain control over what icon displays per column per value based on a series of conditions. An example is listed below:

views()

The views() function is used to pre-define data grid layouts for users to select from. Pre-defined views are passed to this function with callback functions. Each callback is of type ViewDefinition. ViewDefinition is used to build a data grid view. An example is listed below.

hyperlinks()

The hyperlinks() function sets whether email addresses are indicated as links on the front-end.

load()

The load() function can be used to load model relationships dynamically as required. load() take either comma seperated parameters for each relationship or an array of relationship names. Loaded data will be appended to row items.

addSelect()

The addSelect() function, as its name suggests, simply adds a select to the final data gris item list. This is primary used id extra data is required but not automatically select via added columns.

addRawSelect()

Same principle as addSelect() but with raw statements.

mapRow()

The mapRow() function is used to mutate the current pages row items. This function takes a callback function which receives each row item on the current page. It should be noted that any mutations made here are evaluated for every page item (50 by default), and thus more complicated mutations can drastically decrease performance. The below example adds a has_mobile property to the final items list:

get()

The get() function is used to return final DataGrid data array. If passing data to the front-end this function is required. This function is also always called last on the DataGrid instance.

Data grid definitions

Multiple definitions exists to be used with the DataGrid facade. All current available definitions are covered below.

ColumnDefinition

The ColumnDefinition class is used to define advanced columns for your data grid. The ColumnDefinition instance can take the following property functions:

avatar(identifier, preview)

The avatar() function is used to add an avatar to your advanced column. It takes a file identifier for e.g. fileid as well as a boolean for avatar preview. If your query contains joins the identifier should be prefixed with the DB column name. The preview option simply enables users preview the avatar in a larger image on the front-end by clicking on it.

icon()

The icon() function is used to pass an icon to your advanced column. This function works exactly the same as the addIconColumn() we covered earlier.

value()

The value() function is used to pass the DB column value used to display the actual value of the column. This function is similar to the value parameter on the addColumn() function. It should also be noted that when using raw statements the value() function is used for that statement's alias.

rawValue()

The rawValue() function is used when you want to pass raw SQL/MySQL statements if advanced data retrieval is required. It is important to note that when using rawValue() function it is required to also use the value() function to pass an alias to that raw statement. Thus, you DO NOT add an AS section to your raw statement.

subtitle()

The subtitle() function is used to add a subtitle value to your column. The value parameter is the DB column identifier for the value you would like to display. This value is also used as an alias when using raw statements.

rawSubtitle()

The rawSubtitle() function is used to pass raw SQL/MySQL statements for subtitles. It is important to note that when using rawSubtitle() function it is required to also use the subtitle() function to pass an alias to that raw statement. Thus, you DO NOT add an AS section to your raw statement.

type()

The type() function is used to specify the column type of the column itself. Different column types apply different styles, search parameters and filters to that column. Available types are:

• text - Simple text format - uses search
• email - Email formatting and opens email client on click - uses search
• number - Number formatting - uses filters
• perc - Draws a progress bar on the front-end - uses filters
• timestamp - Formats value as timestamp - uses filters
• enum - Formats value as an enum - uses filters
• icon - Adds an icon to column - uses filters

subtitleType()

The subtitleType() function is used to specify the main column subtitle type. Subtitle types are only used to apply formatting on the front-end. Later installments will add searching and filters for subtitles.

label()

The label() function is used to add a label for the column. Label is displayed on the front-end.

enumerators()

The enumerators() function is used to add enum key -> value pairs for available enum values for that column. This function is only used when the column type is enum. Columns of type enum auto-detect enum values when used. This function can however override these values if they render incorrectly.

hidden()

The hidden() function is used to mark that column as hidden. Hidden columns do not render on the front-end. This function is not recommended as the hidden property is usually set through the views() function. If a column should be hidden by default it's better to just not include that column.

searchable()

The searchable() function is used to indicate whether the column can be searched. When applying this option to a column of a searchable type that value will be added to search recommendations.

timestampFormat()

The timestampFormat() column can be used to override the data grid's default timestamp format. This function is only recommended when the column is of type timestamp. An example is: D MMM YYYY.

IconDefinition

The IconDefinition class is used to define advanced icons for columns. This class can be used with the addIconColumn() or the addAdvancedColumn() functions. The IconDefinition instance can take the following properties:

condition()

The condition() function is used to add conditions for specific icons on a column. The function takes 5 possible parameters:

• icon - Icon to be displayed if condition evaluates to true
• operator - Comparison operator - available operators: ===, !=, <, >, <=, >=
• value - The value to be sued in the comparison
• color - The color of the icon to be used
• tooltip - If set the icon will display a tooltip on hover

default()

The default() function is used to specify a default icon to display if none of the conditions evaluate to true. Also takes a color as a second parameter. this defaults to grey.

label()

The label() function is used to specify a label for the icon. This is displayed on the front-end filters menu. If no label is specified it defaults to the column label with an "(I)" attached. Specifying a label is recommended.

ViewDefinition

The ViewDefinition class is used to define views (layouts) for your data grid. The ViewDefinition instance can take the following property functions:

column()

The column function is used to specify default states for column in that view. The column function takes a column identifier as its first parameter and a bool as its second to indicate if that column should be hidden or not.

• value - column identifier - must exist in added column
• hidden - whether column should be hidden or not

An example is shown below:

label()

The label function required and takes a string as an identifier to the pre-defined view. This label is used when selecting this view on the front-end.

search(), filters() & sort()

These functions can be used to pass pre-defined searches, filters and/or sorts as required by the developer. An example is given below:

Definitions will be added for these later

Other available definitions are EnumDefinition and FileDefinition. These are however still under construction and planned for later a release.
