Download the PHP package psenna/lumen-query-builder without Composer

Easily build Eloquent queries from API requests

This package allows you to filter, sort and include eloquent relations based on a request. The QueryBuilder used in this package extends Laravel's default Eloquent builder. This means all your favorite methods and macros are still available. Query parameter names follow the JSON API specification as closely as possible.

Basic usage

Filtering an API request: /users?filter[name]=John:

Requesting relations from an API request: /users?include=posts:

Works together nicely with existing queries:

Sorting an API request: /users?sort=name:

Have a look at the usage section below for advanced examples and features.

Installation

You can install the package via composer:

You can optionally publish the config file with:

Usage

Including relationships

The include query parameter will load any Eloquent relation on the results collection. By default, no includes are allowed. All includes must be specified using allowedIncludes().

You can load multiple relationship by separating them with a comma:

You can also pass in an array of includes to the allowedIncludes() method.

You can load nested relationships using .:

When trying to include relationships that have not been allowed using allowedIncludes() an InvalidIncludeQuery exception will be thrown.

Relation/include names will be converted to camelCase when looking for the corresponding relationship on the model. This means /users?include=blog-posts will try to load the blogPosts() relationship on the User model.

Once the relationships are loaded on the results collection you can include them in your response by using Eloquent API resources and conditional relationships.

Filtering

The filter query parameters can be used to filter results by partial property value, exact property value or if a property value exists in a given array of values. You can also specify custom filters for more advanced queries.

By default, no filters are allowed. All filters have to be specified using allowedFilters(). When trying to filter on properties that have not been allowed using allowedFilters() an InvalidFilterQuery exception will be thrown.

You can also pass in an array of filters to the allowedFilters() method.

You can specify multiple matching filter values by passing a comma separated list of values:

Property Column Alias

It can be useful to expose properties for filtering, that do not share the exact naming of your database column. If you wanted to allow filtering on columns that may have a prefix in the database, you can use the following notation.

Exact filters

When filtering models based on their IDs, a boolean value or a literal string, you'll want to use exact filters. This way /users?filter[id]=1 won't match all users containing the digit 1 in their ID.

Exact filters can be added using Spatie\QueryBuilder\Filter::exact('property_name') in the allowedFilters() method.

The query builder will automatically map 'true' and 'false' as booleans and a comma separated list of values as an array:

Scope filters

Sometimes you'll want to build more advanced filtering queries. This is where scope filters and custom filters come in handy.

Scope filters allow you to easily add local scopes to your query by adding filters to the URL.

Consider the following scope on your model:

To filter based on the startsBefore scope simply add it to the allowedFilters on the query builder:

The following filter will now add the startsBefore scope to the underlying query:

You can even pass multiple parameters to the scope by passing a comma separated list to the filter:

Custom filters

You can specify custom filters using the Filter::custom() method. Custom filters are simple, invokable classes that implement the \Spatie\QueryBuilder\Filters\Filter interface. This way you can create any query your heart desires.

For example:

Ignored values for filters

You can specify a set of ignored values for every filter. This allows you to not apply a filter when these values are submitted.

The ignore() method takes one or more values, where each may be an array of ignored values. Each of the following calls are valid:

• ignore('should_be_ignored')
• ignore(null, '-1')
• ignore([null, 'ignore_me'],['also_ignored'])

Given an array of values to filter for, only the subset of non-ignored values get passed to the filter. If all values are ignored, the filter does not get applied.

Sorting

The sort query parameter is used to determine by which property the results collection will be ordered. Sorting is ascending by default. Adding a hyphen (-) to the start of the property name will reverse the results collection.

By default, all model properties can be used to sort the results. However, you can use the allowedSorts method to limit which properties are allowed to be used in the request.

When trying to sort by a property that's not specified in allowedSorts() an InvalidSortQuery exception will be thrown.

To define a default sort parameter that should be applied without explicitly adding it to the request, you can use the defaultSort method.

You can also pass in an array of sorts to the allowedSorts() method.

You can sort by multiple properties by separating them with a comma:

Selecting specific columns

Sometimes you'll want to fetch only a couple fields to reduce the overall size of your SQL query. This can be done using the fields query parameter. The following fetch only the users' id and name

The SQL query will look like this:

Using the allowedFields method you can limit which fields (columns) are allowed to be queried in the request.

When trying to select a column that's not specified in allowedFields() an InvalidFieldQuery exception will be thrown.

Selecting fields for included models works the same way. This is especially useful when including entire relationships when you only need a couple of columns. Consider the following example:

All posts will be fetched including only the name of the author.

Append attributes

Sometimes you will want to append some custom attributes into result from a Model. This can be done using the append parameter.

Of course you can pass a list of attributes to be appended.

Other query methods

As the QueryBuilder extends Laravel's default Eloquent query builder you can use any method or macro you like. You can also specify a base query instead of the model FQCN:

Pagination

This package doesn't provide any methods to help you paginate responses. However as documented above you can use Laravel's default paginate() method.

If you want to completely adhere to the JSON API specification you can also use our own spatie/json-api-paginate!
