Populating forms based on initial entry

Populating forms based on initial entry

From:

Hello,

I'm relatively new to web development in general and have been building an
application in Flask using the Minitwit app as a scaffolding of sorts.

I know on some online forms there is a behavior where you can put in
something like a username or otherwise and it will populate a drop down box
with fields specific to that initial entry. Such as entering a "state" and
it limiting possible entries to "zip codes" within that state.

I'm wondering if this is a place for jquery or if there is some other
method of doing this specific to flask and if someone could provide some
reference to an example. My google-fu has failed me.

The only way I could think of doing it so far was to do an initial get
request using a submit button to populate the options but I think it would
be nicer to use Jquery. I have the database tables setup to support it, I
just need a way to pre-populate data for the fields based on a userid.

Thanks!

James

Use flask-sijax.  Take a look at the examples.  I would have provided
actual code but I am on a mobile device.  Sorry.

You may also want to look at using AngularJS (angularjs.org).

Here is a list of examples -
https://github.com/angular/angular.js/wiki/JsFiddle-Examples
and a specific example on chained dropdowns - http://jsfiddle.net/KkdfV/35/

Thanks,

I think AngularJS looks a little more on my level, other than it being a
little kludgy. I'll take a look at both!

If you're going through full on front-end client stuff, you might want to 
checkout Backbone (with Backbone.Marionette if you want!).

Similar in concept to AngularJS, but a different approach.  I'm using it 
on several sites I've built.

Or just dust.js for client-side templating if that's what you need.

To be honest, I'm not sure what the best fit would be.

This is going to be used for a user management page. I have a table of
users with multiple fields tied to them. We'll call it 'meta'. So User A
has a Blue Hat, Red Hat, and Yellow Hat. On my user management page I
currently query the 'user' table for all users in my user table for
referencing purposes.  I'm using this management page to select a user by
ID from 'user', and I want to use that user ID to do a call back to 'meta'
for all 'hats' that this user can wear.

I then want to pre-populate a drop down list with the 'hats' so that I can
make sure I can only select data available to a given user for posting new
data to another table.

In my mind this equates to the following process:

Populate User_ID Field. -> Jquery (or manual post) call back to 'meta'
table for * where user_id -> jinja filter to populate drop down box for x
in 'meta' query.

So if I can find a simple way to do it in Jquery that would be nice, but
otherwise I am sure this can be done with a simple 'update' route that
queries and has an endpoint back on my form.

Okay, just got back.

Yes, you can use jQuery. Sijax is a python library that allows you to pass
Ajax requests without having to take care about the rest of the things
deemed unnecessary. Flask-Sijax is merely an extension that allows you to
utilize the library. So if you were to have a form that has a field as per
your example:

<form method="POST" action="">
  <label>Hats</label>
  <input type="text" label="hats" name="hats" id="hats" />
  <a href="javascript://" onclick="Sijax.request('pullallhats',
[$('#hats').value()]);>Get hats</a>
  <!-- This will send a trigger to query all the results related to the
input field -->
</form>

In order to get the things to display beneath the field you will need
jQuery animation and stuff. That you need to look into on your own :)

But this has worked for me, I have done this before.

Oh I forgot the Python bit that will handle this request:

@flask_sijax.route('/foo')
def foo_handler():
    def pull_hats_handler(obj_response, myhatinput):
          #this is where you pull the hats from the database and update it
to your page
          myhatsresult = db.query.get_results_for_hats_or_whatever()
          return obj_response.script('') #this is where you pass the result
to the page using a script or a simple alert: e.g.
obj_response.alert(myhatsresult)

    if g.sijax.is_sijax_request:
     g.register_callback('pullallhats', pull_hats_handler)
     return g.sijax.process_request()

return render_template('foo.html')

The thing about obj_response.script() is that you can pass triggers with
the data to a predefined script on the page.

So if I had say a script that shows a menu beneath the field you can just
do this from the Python code

return obj_response.script('#script_id.show()')
subject to the condition that your script shows on show(). You can
experiment with Bootstrap's predefined scripts. It has a simple hide()
show() and toggle() predefined. I am sure you will find a dropdown if you
look through the latest version of Bootstrap, otherwise, it's easy to write
a simple script that shows a drop down having certain content.

Good Luck.
