sorry if you do not understand the translation but I need help with Django 1.4, the fact is that I need an example or a tutorial how to create multiple dynamic backend comboboxes in html form, the combobox data are obtained from the database and should be saved.
An example http://www.martiniglesias.eu/demos/combobox/index.php
The idea of this example is using Django 1.4, Mysql and Jquery.
Any question, if not let me know please understand, I will be attentive to your feedback.
Thank you!.
You can use dajaxproject to get data for dynamic combobox, here is an example: http://www.dajaxproject.com/forms/

I have been using formtools in Django to render lengthy forms for my application. I have managed to do this(Fill in forms and submit data into the DB). Something got me thinking, what if I didn't complete all the steps in filling up the forms and want to save the progress and resume filling some other time? I have searched online for such information and haven't succeeded.
First, Is this possible with formtools? If yes, How do I go about this?
Thanks in advance for the help.
Look at formtools.wizard.views.SessionWizardView. As you can guess it uses session storage internally. Also formtools provides cookie-based solution out of the box.
I want to create simple upload form on my django site where users could upload their gpx files but I want to give them possibility to preview their points and lines on map before they proceed with submiting it.
I have some basic knowledge of working with django forms but I'm not sure how to convert that gpx data and display it on map.
I hope you can tell me at least where to start because I'm completely out of ideas.
Thanks
Well, if you use Django then you could probably extend it with Geodjango which provides you easy and nice way to create geometry fields for your models (points,lines, poligons).
In case you decide to use Geodjango for this purpose then please check my blog post http://ipasic.com/article/uploading-parsing-and-saving-gpx-data-postgis-geodjango/
I've described there process of uploading,parsing and saving gpx file to spatial database (like Postgis).It could help you to get an idea.
I didn't describe how to display it on map but it shouldn't be problem. I would recommend you to use Leaflet or some other javascript mapping library for it.
However, that's to much for writing right now.
I hope that helps.
I am working on a django project with complex forms. In one of my form fields I need following functionality...... Its the text field. As the user starts typing the value the suggestions from existing database should appear in dropdown. Can anyone help me out with this ? Just similar to autocomplete but able to add new values.
This is going to be something in the JQuery/AJAX side of things, not Django. I would read up on the autocomplete functions of JQuery and use AJAX to call your DJango code and receive a populated list, which then displays to the user.

If you don't want to deal with JavaScript, you can use a django application called django-autocomplete-light.
You can learn more about it (and get it) here: https://github.com/yourlabs/django-autocomplete-light
I'm new to python and the Django framework. I am dealing with lots of forms in my application which is half way developed by the person working in this position earlier. I now need to change the form to incorporate the "Add additional details" button to my existing form.
Can anyone help me out with this? Do let me know in case you need any additional information from my end.
I suggest you read the Forms documentation: https://docs.djangoproject.com/en/dev/topics/forms/?from=olddocs
I don't really understand what you mean by "Add additional details". I'm assuming you want to just add additional items to your form.py of your app, be it model data? Again read the doc's they really helped me.
Is the form using an (inline) formset?
You need to use javascript or jQuery to insert a new set of fields into the web page. The formset management values need to be updated as well.

I am planning to use Django-Haystack to add a search component to my site. This will take care of the data I have in my models.py. I however also want data which is not in a model, but part of templates to be searchable. How can I get this.
There is a django app called haystack-static-pages that should help here. It's not been updated for a while so I doubt it will work with haystack 2.0, but I hope this might be of some help to you:
