![]() ![]() WHERE (user.name = admin) AND (node.sticky = 1 OR node.promoted = 1) Like mentioned in the grouping section, you can put groups into other groups. Grouping grouped filters: Get nodes that are promoted or sticky and created by admin You don't really have to add the and-group but I find that a bit easier usually. WHERE user.name = admin AND node.status = 1 filter=ANDįilter=and-groupįilter=statusįilter=1 Now let's combine some of the examples above and create the following scenario. Grouping filters: Get nodes that are published and create by admin. It is better to use an index to create unique array elements. While these work when typed into the URL, Guzzle and other http clients will only create one value as the array key will be seen to be same and override the previous value. Tip: when utilizing square brackets for multiple values filters, do not just use empty square brackets for a new value. ![]() NORMALįilter=uid.nameįilter=INįilter=adminįilter=john Note that I added two square brackets behind the value to make it into an array. &filter=%3D ',įor this example we're going to use the IN operator. If we were filtering on a user's first name, a condition might look something like this: ?filter=field_first_name To do that, we represent each condition with key/value pairs. In the JSON:API module, we can't make it look as pretty as that because we need to make it work inside a URL query string. $field is the field of the resource identified by its 'path'.In pseudo-code, a condition is a thing that looks like this: A 'value' is the thing you compare against.An 'operator' is a method of comparison. ![]() A 'path' identifies a field on a resource. ![]() Remember, a condition tells you a TRUE or FALSE thing about a resource and some assertion you make about it, like "was this entity created by a particular user?" When the condition is FALSE for a resource, that resource won't be included in the collection.Ī condition has 3 primary parts: a path, an operator and a value. "b" and "c" are members of "a" in an AND group. "d" and "e" are members of "c" in an OR group. You can think of those nested sets like a tree: Conventional representation: Those sets can be nested to make super fine queries. Conditions assert that something is true and groups let you compose those assertions into logical sets to make bigger condition groups. The fundamental building blocks of JSON:API's filters are conditions and groups. Collections are JSON:APIs API-First replacement for exported "REST displays" in Views. Unlike the REST module that comes with Drupal Core, JSON:API does not export Views results. If you're not a newcomer to Drupal, you've probably already used the Views module for these kinds of things. Finally, we'll see a number of filter examples taken from the real world. After that, we'll show you a few shortcuts that make writing filters a little faster and less verbose. We're going to work our way up from the very basics. All of that power comes with a bit of a learning curve though.īy the end of this article, you'll be able make complex queries and reason about problems you may face, like "how do I get a list of an author's articles about llamas or the worlds fastest member of the animal kingdom, the peregrine falcon?" The JSON:API module has some of the most robust and feature-rich filtering features around. This matches all resources with "field_name" equal to "value" and "field_other" equal to "value". The simplest, most common filter is a key-value filter: This guide will teach you how to build filters like a pro. Without filters, you can't get only your articles or only articles about llamas. However, when you make an unfiltered request to a collection endpoint like /jsonapi/node/article, you'll just get every article that you're allowed to see. In a decoupled site, they're what you use to create things like a "New Content" list or "My content" section on the client-side. ![]()
