    <p>I have 3 classes "campaigns", "relationships" and "locations" on parse.com I have a query to hit the campaigns table and get its information by</p> <pre><code>var query = new Parse.Query("Campaigns"); query.find({ success: function(results) { }, error: function(){ response.error("failed to get a respose"); } }); </code></pre> <p>Now I want to hit the locations table by navigating through the relationships table. (the relationships table has a column which stores the object IDs of the campaigns in the campaigns class). How do I access the corresponding data from the "locations" table? I know I have to make another query but I cant find the correct syntax.</p> <p>for android (java) the syntax would be something like-</p> <pre><code>ParseQuery&lt;ParseObject&gt; query = new ParseQuery&lt;ParseObject&gt;("Campaigns"); ParseQuery&lt;ParseObject&gt; query2 = new ParseQuery&lt;ParseObject&gt;("Relationships"); ob2 = query.find(); for (ParseObject object : ob2) { ParseObject Locations = new ParseObject("Campaigns"); query2.whereEqualTo("campaignIDString", object.getObjectId()); query2.include("locationID"); //the pointer column it must have try { ob = query2.find(); //this holds the locations Table data } } </code></pre> <p>Sorry about the formatting, not very used to SO formatting yet</p>

    1. COHow many locations do you expect to have per campaign? Do you need any extra information about a campaign/location join or is it a simple relationship? Depending on the answer to those questions there might be a much simpler way to do what you want to do.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
