I've a website implemented using emberJS, It has a "contact us" page, now when someone fills up the form & submit the data I need to do implement a POST request. Do I need to create a model for this ? right now I just did $.post(...).
I just wanted to know is there any much cleaner(or may I say emberish way) to implement this ?
IMHO, a ContactRequest model seems like the most idiomatic way to go about this. That way you can use the regular Ember facilities and later add features like a backend that shows pending contact requests and - depending on your use case - does things like sorting them by subject area etc.

I'd like to implement select all button (e.g select all and deleting) in Django 1.9.7 but I can't find any post about it in Google Since, I'm not a non-native-english person, I'm not good at googling in correct english. Could anybody give me advices or keywords so that I can googling based on it?
Well this depends on how you implemented your table with Django. Putting javascript/bootstrap/etc aside, there are some samples on how you can implement select all in javascript. Like this.
Deleting those items requires defining a form and processing it's data in the serverside and deleting your model items. This also depends on how you are passing data between your view and your model.
Maybe this isn't the correct place to ask, but I asked this question on Joomla forums and did not get any answers. If someone can help me or at least point me in the right direction, I would really appreciate.
My question is: In a Joomla 2.5 website, I want to create two different kinds of forms for registering users. Maybe "registering" isn't the correct term. I want to create something like a very simple database which will hold records for two kinds of users:
- one which will be interested in working in projects, so in this case the form will have more fields and specific details to fill
- one which will be interested only in receiving newsletters from the site, and in this case only basic contact information will be required.
I did some research and found an extension named AcyMailing which can handle the newsletters for example, but I need to have all my potential users registered as Joomla users. I would like to avoid that if possible. If not, how can I differentiate the two kinds of users on registration, so the visitor can choose which option he wants and in this case, add more information to the registering process, if possible.
I'm not very experienced with Joomla, but since the site in question is already implemented using it, I don't have much choice.
Thanks in advance!
Chronoforms. Most definitely here would be a great use for their AWESOME free component. Your forms can work as registration forms (should you desire that); or can also just be free standing forms that log the information filled out on them to your database which you can later use however you would like (i.e. compiling a mailing list or something of that sort).
The form wizard makes it almost bullet proof, then you can have a form for 1 type of user to fill out, and a form for a different user build different ways.
That will get you the data - in order to mass mail those people you'll need a way to extract their emails out of the database (or find an email component that will let you email based on certain fields in the database or what have you); but it's totally possible and would be easily done I think with 1 simple mySQL query on your database table created by chronoforms.
In terms of something that will solve your issue quickly and get you the info you're looking for in two separate ways - chronoforms will do that exactly.
I am wondering how one would setup a multi-step form in CFWheels.
Clearly I would need to store form data in the session etc as I go, but I would like to know the best approach from a wheels perspective to do this the 'wheels way'.
Do I have just one action in my controller that handles this? Or would it be best to seperate each part of the form out into separate actions?
Advise on this and possible code examples would be much appreciated.
Thanks,
Michael
The way I've done it in past is use Ajax calls and a jquery modal.
though the jquery modal is not important, I just like the aesthetic. a simple div replacement will also work.
If you cannot be sure that the users can use AJAX then it won't work for you, but you might be able to use a popup window.
The advantage of using Ajax calls for multi-step forms is that you can adjust the form content from one step to another. Another advantage is that you don't have to store user data in the cache or session. Because each time you send a form, you can use the POST or GET.
For this to work, the quickest way of setting this up is to use the plugin called RemoteFormHelpers. Then each step of the form would be a different controller (or the same one with a switch statement based on the data passed)
I think this is a pretty versatile way of doing this, but you cannot do a form that uses file-uploads, well not easily as ajax won't let you do it without some serious pain.
I am writing a Django application and using the built-in ORM. I would like to create functionality to provide a form but the template for that form needs to be built on admin side of the application and can change over time.
For instance, initially they have a form that asks for first name, last name but later if they decide to add birthday field admin should be able to go to this template page add birthrate as new field and on client side, users start seeing it. Is there anything already in place that can be used? I was thinking of using something like this but decided to check here and see if there is something better available.
Is it this what your are looking for?
I have never heard about any library for that, because you have pretty much different approaches to handle that!, but check the link, he is explaining better those approaches.
What is the best way to conditionally display a field in the admin depending upon the values of other fields?
In particular I'm thinking about the add_form and change_form. Whenever a certain choice is selected I'd like to hide or disable some fields.
I'm thinking that this might require a javascript solution, but am wondering if there is a better (i.e. builtin) way to do this.
Bernhard is right. You might be able to hack the admin view and template to conditionally show/not show widgets for a field, but if you want to do it dynamically based on user behaviors in the admin, you'll be using javascript.
It's not so terrible, though. At least the Django admin templates have model- and instance-specific ids to give you granular control over your show/hide behavior.
My answer may sound esoteric - but I suspect the design direction you may be taking could benefit from some reconsideration. When an interface requires that much TLC to resort to AJAX to make for a superior UX I am inclined to not use Admin interface for that.
My personal view of the Admin interface of Django is that it is a great freebie that gives me an instant CRUD view at a basic level. I would refrain from piggy backing on it for those who need a more user friendly interface (even if some of these users are handling admin functions). You will acquire technical debt in trying to do these type of Ajax UI/UX and complex form validations using the Admin interface.
I think you should be able to create your own ModelForm and specify that the admin uses that (https://docs.djangoproject.com/en/1.7/ref/contrib/admin/#django.contrib.admin.ModelAdmin.form).
Use the _init__() method of the form to selectively display the fields.
I will give it a try and update this answer if it works.
(Actually re-reading the question, it depends. If "values of other fields" is set before the page is loaded, this idea should work. If you want an instant response - click one field and another appears/disappears, yes you will need JavaScript).
