relationships

I've been looking over relationships in Laravel 4 in the documentation and I'm trying to work out the following. I have a table in my database called 'events'. This table has various fields that mainly contain ID's that relate to other tables. For example, I have a 'courses' table. The events table contains a field called 'course_id' which relates to the ID of the 'id' field in the courses table. So basically, I'm after some advice on how you go about relating the two (belongsTo()?) and then passing the connected data to the view. Here is where I am at so far http://paste.laravel.com/pf3 . I

In Laravel 4; I have model Project and Part , they have a many-to-many relationship with a pivot table project_part . The pivot table has a column count which contains the number of a part ID used on a project, e.g.: id project_id part_id count 24 6 230 3 Here the project_id 6, is using 3 pieces of part_id 230. One part may be listed multiple times for the same project, e.g.: id project_id part_id count 24 6 230 3 92 6 230 1 When I show a parts list for my project I do not want to show part_id twice, so i group the results. My Projects model has this: public function parts() { return $this-

Is it possible to create/delete different databases in the graph database Neo4j like in MySQL? Or, at least, how to delete all nodes and relationships of an existing graph to get a clean setup for tests, e.g., using shell commands similar to rmrel or rm ? Peter Neubauer You can just remove the entire graph directory with rm -rf , because Neo4j is not storing anything outside that: rm -rf data/* Also, you can of course iterate through all nodes and delete their relationships and the nodes themselves, but that might be too costly just for testing ... even more simple command to delete all nodes

I have this (simplified) table structure: users - id - type (institutions or agents) institutions_profile - id - user_id - name agents_profile - id - user_id - name And I need to create a profile relationship on the Users model, but the following doesn't work: class User extends Model { public function profile() { if ($this->$type === 'agents') return $this->hasOne('AgentProfile'); else return $this->hasOne('InstitutionProfile'); } } How could I achieve something like that? Lets take a different approach in solving your problem. First lets setup relationship for the various models respectively

Is it possible to set up a double relationship in activerecord models via the generate scaffold command? For example, if I had a User model and a PrivateMessage model, the pm table would need to keep track of both the sender and recipient . Obviously, for a single relationship I would just do this: ruby script/generate scaffold pm title:string content:string user:references Is there a similar way to set up two relations? Also, is there anyway to set up aliases for the relations? So rather than saying: @message.user You can use something like: @message.sender or @message.recipient Any advice

Is there a way to merge 2 relationships in laravel? this is the way it's setup now, but Is there a way I could return both merged? public function CompetitionsHome() { return $this->HasMany( 'Competition', 'home_team_id' ); } public function CompetitionsGuest() { return $this->HasMany( 'Competition', 'guest_team_id' ); } public function Competitions() { // return both CompetitionsHome & CompetitionsGuest } Try out getter method for property which returns merged collections returned from relations. public function getCompetitionsAttribute($value) { // There two calls return collections // as
