[ckan-dev] Alter resource in grid view

[Dominik Moritz]

Hey,

That sounds like you should look at how to limit the data shown and not the data served. If your use case is very specific, you should write your own preview. Look at this answer as a starting point: http://stackoverflow.com/a/17743079. If you data is in the datastore, you can easily filter the results to only get a limited number of rows in the overview view. The full record can then be loaded via Ajax. I don't think that you need to edit any controllers. 

You were talking about the recline grid view, right?

Cheers,
Dominik

Ive added a controller etc., to enable viewing the full record - but I'm trying to find out how to change the data in the grid display to only show some of the fields.
