I want to modify a record from db.project, and there are a reference field in db.project. So I use SQLFORM.factory to add field to put reference list name.
the code I paste is simplify version here is full code form = SQLFORM.factory(Field('list_name', 'string', label='List Name'), db. project, db.feature, table_name='project',upload=URL('download')) for t in [db.project, db.project_feature]: query = t.id == project.id if t == db.project else t.project_id == project.id __copydata(db(query).select(limitby=(0,1)).first(), form.vars, t.fields) Anthony於 2016年2月28日星期日 UTC+8下午9時29分52秒寫道: > > Sorry, still not clear what you are trying to do, and you have not > explained why you are iterating over the Fields of the db.project table. > > On Sunday, February 28, 2016 at 3:48:26 AM UTC-5, killzane wrote: >> >> Because I want to add other field to the form so I use SQLFORM.factory. >> >> And this is my __copydata method >> def __copydata(src, dest, fields): >> if src: >> for k in fields: >> if src.has_key(k): >> dest[k] = src[k] >> return dict() >> >> >> >> Anthony於 2016年2月26日星期五 UTC+8下午9時08分13秒寫道: >>> >>> >>> for t in db.project: >>>> query = (t.id == request.vars.id) >>>> __copydata(db(query).select(limitby=(0,1)).first(), form.vars, >>>> t.fields) >>>> >>> >>> The above is confusing and cannot be the actual code, as it would raise >>> an exception.
