actionview - Ruby on rails nested form model -


I'm trying to use auxiliary form_for nested rails, but I am getting the following error:

BlogPage (# 49,859,550) expected, array (# 31117360) found

here are my model objects: 

  class blog & Lt; ActiveRecord :: Base # table configuration set_table_name "blog" # model configuration belongs_to: item has_many: blog_pages accepts_nested_attributes_for: blog_pages ,: allow_destroy = & gt; True End Class Blog Page & lt; ActiveRecord :: Base # table configuration set_table_name "blog_page" # model configuration belongs_to: Blogs end

The Form I is generated (the unnecessary HTML left out): < / P> 

  & lt;% form_for: blog ,: url = & gt; {: Action = & gt; : Making} do Blog_form | & Gt%; & Lt;% = blog_form.text_field: Title ,: style = & gt; "Width: 400px"%> & Lt;% blog_form.fields_for: blog_pages do | Page_fields | | & Gt%; & Lt;% @ blog.blog_pages.each do | Page | & Gt%; & Lt;% = page_fields.text_area: Content ,: style = & gt; "Width: 100%" ,: cols = & gt; "10",: rows = & gt; "20"%> & Lt;% end% & gt; & Lt;% end% & gt; & Lt;% end% & gt;   > { "Blog_pages" => { "content" => "This new blog entries is content."}, "Title" => "This is a new blog entry" "full" => "1"}, "authenticity_token" => "T1Pr1g9e2AjEMyjtMjLi / ocrDLXzlw6meWoLW5LvFzc ="}  
  There is BlogsController making that action is executed:  < / P> 
  Class BlogsController & LT; ApplicationController def new @blog = Blog.new # This is the line where the error is thrown. Set up a page for #new blog so that the view is displayed properly @ Blog.blog_pages [0] = BlogPage.new @ blog.blog_pages [0] .page_number = 1 Reply Do not Do It. Format | Format.html # new.html ARB goes into the scene Format.xml {Render: xml = & gt; @blog} format.js {render: layout = & gt; Bad} end-end DRF @ blog = blog.new (param [: blog]) response_to do | Format | If @ blog.SaveRender: Action => : Show and Flash [: Notice] = "An error occurred while saving the blog entry." Render: Action = & gt; : End of the new end  
 
 I appreciate it if someone can help me with this. I am still new to the Ruby and can not solve the problem on my own by rail framework and googling. 
 
 Thank you.

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...

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...
