Re: Dynamic model fields using mysql?

One question I'd ask would be why you wouldn't just save the files either on disk or even in the database (using the BLOB datatype) if it absolutely had to be in the database... then if you needed to manipulate/display/read them at a later date you would just load the files in question. If

I have close to 600 users split by 20 or so offices. We have a helpdesk form (using ModelForm) which displays an initial user list based on the office, or no users if an office is not selected. An AJAX function on the front end dynamically changes users in the drop-down based on the office

So, the value is a string, but the widget you want to display to the user should be changed according to the key value? Probably you have to create your custom tag (e.g. render_value_widget) and then use something like {% render_value_widget key value %} in your view. If you provide the same name

Hi there, this might be a trivial question but my search within the django documentation and google didn't give me any helpful results. In Ruby on Rails you can simply do this x = Model.new({:param_x => 'x', :param_y => 'y'}) where the params are some model fields. The hash you can provide
