hi,
i'm very new to django (basically a few days) and have read almost all
the docs, wikis and mailing list archives (well the topics which
interest me at least). I have a few questions I was hoping anyone on the
list could help me with concerning customizing the behaviour of the
admin interface.
1. Are there hooks to manipulate the data before its sent to the
template for rendering (on both list and edit screens) ?
You can override the urlconf for that page with a wrapped or replaced
version of the appropriate function. There is a ticket for a postload
tag somewhere as well, but it doesn't exist atm.
thanks for the tip. I'll try that.
2. Are there hooks to manipulate the data after its submitted before
saving to the database.
Ditto, or use pre_save.
3. I know that you can customize most of the admin templates but can you
customize the admin templatetag templates (apologies for the double post
regarding this point in my other thread).
The templates are all loaded in the same way, you can override them all.
I looked at the code, and the template tags eg.
templatetags/admin_list.py "admin/change_list_results" is loaded a bit
differently.
4. Can we change the template {{ variable }} to something like
${variable} I don't mind the {% %} but {%starttag%}{{var}}{%endtag%}......
You can assume this is not going to change, it would break too much for
very little benefit. I guess you could monkey patch
django.core.template.VARIABLE_TAG_START and
django.core.template.VARIABLE_TAG_END if you wanted to. It would be kind
of silly though.
You're right about the little benefit, but this syntax ${var} or $var is
very widely used in many template solutions across all languages and
provides a level of familiarity to most template users. Easier migration
and therefore wider adoption may prove a benefit which isn't as obvious now.
5. Can we assume that thirdy party template libraries will never be able
to reuse any of the admin templates unless someone re codes them in the
third part template.
Yes. Although you could make a bit of functionality for another language
which used a django template embedded in it. It would probably be
confusing in use, however.
Thanks for taking the time on answer my questions.
