kandi X-RAY | NeoEloquent Summary
Due to the fact that relationships in Graph are much different than other database types so we will have to handle them accordingly. Relationships have directions that can vary between In and Out respectively towards the parent node. Represents an INCOMING direction relationship from the related model towards the parent model.

QUESTION
I'm working on a web based app,and the Tech stack is : VueJS,for the presentation layer, Laravel (PHP) for RESTFUL API service,and a nosql graph based database called neo4j. Here is the problem context, I have a model called Post, and attributes that are defined here are shared all the post type,so all of them will have it:

I'm creating an api rest that it interfaces to a graph db already filled by nodes and edge that describes events and exhibit's positions inside several museum that are charactirized by zones. In particular there are some edges between exhibits and zones that has properties like start time and coordinates. Start time is a property that is in according with DateTime neo4j format, below an example:

Answered 2018-Oct-16 at 07:02I also encountered the issue and have not been able to find a way around this in the way that you want. It is in the neoeloquent library itself as far as I can figure out. However I have come up with an alternative which is not ideal since it would be better to be able to do it with the library but it works.
I have written a RawQueryService which can take a raw Neo4j query and retrieve the output as an associative array.
The RawQueryService is as follows:

QUESTION
I'm new of lumen and neo4j, I'd like to add some properties to a specific relationship between two labels.
For example if we suppose that there is a many to many relationship between the Exhibit label and Zone label that is characterized by coordinates property, how can I retrieve the coordinates attribute?
Reading the neoEloquent documentation, I have understand that for retrieve the edge between two labels I have to follow a procedure like that there is present inside the function findZone:
...ANSWER
Answered 2018-Oct-15 at 14:03Your PHP code is correct, however Neo4j is case-sensitive, try changing $this->belongsToMany('App\Zone', 'BELONGS_TO'); to $this->belongsToMany('App\Zone', 'belongs_to');
And yes, your code translates to the query in your question.
EDIT
For the error you are getting try $exhibit->zones()->edge($exhibit->zones) instead of $exhibit->zones()->edge() This will not work if the returned value of $exhibit->zones is an array, you will have to iterate over this array or specify a specific model on the other side of the relationship, i.e.:
To retrieve all edges:
QUESTION
I want to create an api rest using lumen that it will comunicate with neo4j, for this purpose I'm using NeoEloquent. I've already read the NeoEloquent's documentation but I'm confused. I've understand how lumen it work with a relational database, there is a model, a controller, every action that I want to do on my db pass through a routes that specify the method to use, but I don't understand how this work with a graph database. In particular I don't understand how can I create new label, retrieve all label and relationship using the Http methods. I've try to follow the same procedure that it's explain in this guide (clearly readapting it to my use case) but without success.
ExampleLet we say that we have two labels with a many to many relationship, this labels will be Exhibit and Zone. We want to retrieve the zone that is associate to the Exhibit that has a specific identificator. So, the query will be something like this:

Answered 2018-Oct-11 at 16:47In order for NeoEloquent to make the connection between your models you also need to define the 'related' model, with the line $this->belongsToMany('Zone', 'belongs_to'); specifies that this class is related to another class (i.e. a node in the graph database) and connected with a relation.
In order to fix your problem you will need to specify this class with at least the following:
