[ckan-dev] Customizing Forms in 2.0a

Fri Dec 28 09:16:19 UTC 2012

The Geo-Plugin works now. But I had to create a new dataset, it didn't adopt to the existing ones. 
I have still issues understanding the concept:

In the method setup_template_variables() you can add properties to the c-Object, which are available
In the template. Like in c.country_codes. It seems that this just works in the new_package_form.html template.
In the read template you access the data with c.pkg_dict['country_code']. I really don't get it. Why the difference.
I tried to add some custom data to test the functionality e.g. c.test = 'hallo', but this is not working at all.
So my question: Which data is when passed to the template and how can I access it?

Thanks again.

I basically took the complete plugin as it is. I get the following error message when I try to edit a dataset:

UndefinedError: 'dict object' has no attribute 'tracking_summary'

I attached the entire traceback. The plugin is still working with the old template engine. Might that be a problem?
I guess I have some issues understanding the whole concept of adding a form field. I don't want to do any complex stuff, just adding some simple extra fields. 

Thank you very much!

It should still be working. What problem are you having with it?
