Hello,
Just thinking about the best way to build an Order form that would (from user-perspective):
- Allow adding multiple items.
- Each item has Name, Job Type drop-down and File upload.
- User can add or remove items.
- User must provide at least one item.
- All the items should be validated (eg: Name, JobType and File are required).
- When he hits the Submit, an Order should be created with all the items in it.
So the model looks like: User -1---*-Order-1---*- OrderItem-*--1-JobType. Additionally OrderItem includes number of attributes, let's say name, file.
Now I would like to have as skinny controller as possible. Better with the 'standard' code like:
class OrdersController < ApplicationController
def create
@order = Order.new(params[:order])
if @order.save
redirect_to account_url
else
flash.now[:error] = "Could not save Order"
render :action => "new"
end
end
end
The most interesting thing is how a view should look like so that rails automatically binds all the values posted to the correct objects?
For now I don't worry about degradation from JavaScript, but rather the template for the items to be added and linking all that with the validation (probably as a partial).
I expect a template to look like the one below, but not sure.
<input type='text' name='order[order_items[name[]]][]' />
<select name='order[order_items[job_type[]]][]'>...</select>
<input type='file' name='order[order_items[file[]]][]' />
I have to clone this template in order to add item using JS.
So the answer should:
- Include the view or part of it that demonstrates:
- correct binding of the post values;
- correct validation for all items;
- Include related part of model.
- Include changes to the controller IF and ONLY IF necessary.
- (JavaScript is not required)
Ideally I would like to see a sample if somebody knows one (maybe somewhere on GitHub).
And the last note, please, check your solutions before posting.
Thanks,
Dmitriy.
