[ckan-dev] Reading error after adding a new field in Organization [ codes in github]

Tue May 13 03:39:49 UTC 2014

Today I ran two different tests, and I found:

Case 1:

If I defined the method def db_to_form_schema  like below:
    def db_to_form_schema(self):
        # Import core converters and validators
        _convert_from_extras = tk.get_converter('convert_from_extras')
        _ignore_missing = tk.get_validator('ignore_missing')

        schema = super(NlmpProjectFormPlugin, self).form_to_db_schema()

        default_validators = [_convert_from_extras, _ignore_missing]
        schema.update({
                       'project_leader':default_validators
                       })
        return schema

Response from API request: http://127.0.0.1:5000/api/3/action/organization_show?id=project1
result: {
packages: [ ],
display_name: "Project1",
approval_status: "approved",
image_display_url: "",
title: "Project1",
name: "project1",
is_organization: true,
state: "active",
image_url: "",
groups: [ ],
users: [
{
capacity: "admin",
name: "baiqif"
}
],
project_leader: "P1",
type: "organization",
id: "b8728257-6e11-40c4-90ff-cea0f7289f71",
tags: [ ],
description: "This is a project1"
}
}

CKAN page http://127.0.0.1:5000/organization/project1 returned exception: ValidationError: {'name': [u'Missing value']}

However, http://127.0.0.1:5000/organization/edit/project1 returned a correct page !!!

--------------------------------------------------------------------
Case 2

If I defined the method def db_to_form_schema  like below:
    def db_to_form_schema(self):
         pass

Response from API request: http://127.0.0.1:5000/api/3/action/organization_show?id=project1  and CKAN page http://127.0.0.1:5000/organization/project1 returned an normal page.

The difference of response between case 1 and case 2 are:
Case 2 has more info about user;
Case 2 treated project_leader as an extra field --  It is understandable.

Wonder if "user" schema causes the "ValidationError: {'name': [u'Missing value']}"

Subject: [ExternalEmail] [ckan-dev] Reading error after adding a new field in Organization [ codes in github]

I have developed a plugin which adds a field "project_leader" into "organization' . I can use API method to retrieve this project and get the value of "project_leader".  However, when I use CKAN page, for example: http://127.0.0.1:5000/organization/project6, it returns me "ValidationError: {'name': [u'Missing value']}"
 I have commit my code to https://github.com/baiqif/ckanext/tree/master/nlmp

There are two main classes in plugin.py:

ExampleIDatasetFormPlugin  -  it is the example the CKAN webiste gave

NlmpProjectFormPlugin - add a 'project_leader' to 'organization'.  This is the example I got errors.

 It can write 'project_leader' field into the CKAN database and I can read the value for API request. But CKAN web reports an error of {'name': [u'Missing value']}

Many thanks for your help

Bai
