ruby on rails - How should I structure controller actions that share templates? -


Assume that I have a user model, and a invoice Model related_to: user with association.

Now I am creating a new action for my InvoicesController , and the scene will be sung, a selection of scenes for this user's selection- Element will be from this invoice.

So I need to bring those users somewhere; My tendency is to leave out seeing this kind of thing, I end up with: 

  def new @users = User.all end

form Submit create . When creation fails for some reason, I render the view of the action of new action. 

  def invoice = invoice. New Perm [: Invoice] If Invoice. Flash [: notice] = 'invoice created!' Redirect_to: Action => 'Show' ,: ID = & gt; Invoice.id other @ user = user.all render: action = & gt; The end of the 'new' end

But as you can see, in order to reproduce the new action, I have to bring users back .

This is just an example, but keep in mind that I have some forms with many select elements filled with databases, or similar constructions

  • am I just User.all

    > In my opinion?

  • Should I call new to create to fetch for me?
  • Or something << li>

For this I before_filter was using. For example, you do something like this: 

  before_filter: fetch_all_users ,: only => [: New, Create] Protected def fetch_all_users @users = User.all end

For 90% of my controllers I use the plugin It requires the controller to write for CRDUD controllers Reduces the amount of code, it also means that you can cut the necessary tests to write.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
