Rails Validation | add class to surrounding <div> -

-

itemprop = "text">

Railway questions are for default behavior fields for error verification, such as error-style divisions around input fields, such as < / P> 

  & lt; Div class = "type-text" id = "pre_negotiation_value_div" & gt; & Lt; Label = "contract_budget_holder" & gt; Budget Holder & lt; / Label & gt; & Lt; Div class = "fieldWithErrors" & gt; & Lt; Input id = "contract_budget_holder" name = "contract [budget_holder]" size = "30" type = "article" value = "" /> & Lt; / Div & gt; & Lt; / Div & gt;

I'm trying to complete, to enclose the label and input field with the classified div tags, so that they look like the following: 

  & Lt; Div class = "type-text fieldwhetherers" id = "pre_negotiation_value_div" & gt; & Lt; Label = "contract_budget_holder" & gt; Budget Holder & lt; / Label & gt; & Lt; Input id = "contract_budget_holder" name = "contract [budget_holder]" size = "30" type = "article" value = "" /> & Lt; / Div & gt;

Any ideas how to complete this? Can you hook javascript into ActionView :: Base.field_error_proc?

I'm new to the rail, I'm sorry it's super easy!

Thank you for your help.

It's not very easy to do exactly what you want , But if you have ERB: 

  & lt; Div id = "pre_negotiation_value_div" class = "type-lesson" & gt; & Lt;% = f.label: name% & gt; & Lt;% = f.text_field: name% & gt; & Lt; / Div & gt;

You will get HTML like this: 

  & lt; Div id = "pre_negotiation_value_div" class = "type-text" & gt; & Lt; Div class = "fieldWithErrors" & gt; For label = "foo_name" & gt; Name & lt; / Label & gt; & Lt; / Div & gt; & Lt; Div class = "fieldWithErrors" & gt; Input id = "foo_name" name = "foo [name]" size = "30" type = "text" value = "" /> & Lt; / Div & gt;

Where both the label and the text fields are fields, the ether's DID will be around them. Based on how you want to style it, it can be great if it is not enough, then you have to do a custom assistant like this:

Viewer :: Helper :: Formbild DEF labeled_input (method, option = {}, and block) (option [: class] || = "") & lt; & Lt; If the "objectWithErrors" @ object.errors.on (method) ActionView :: Helpers :: InstanceTag.send (: alias_method ,: original_error_wrapping ,: error_wrapping) ActionView :: helper :: instantatge send (: define_method,: error_wrapping, Proc New {| Html_tag, has_error | html_tag}) @ template.concat (@ template.content_tag (: div, @ template.capture (& amp; block) option)) ActionView :: Help: :: InstanceTag.send (: alias_method,: < / Code>

It has been inserted into config / initializers / labeled_input.rb . This is a bunch of ruby ​​meta-foo, but what it does is put the "Fieldwise Authors" class on the external field, it is temporarily error_wrapping to the InstanceTag method Redefines so that the internal label and text_filtered tags do not have a "Fieldwise Arrows" division around them. You use it in the ERB: 

  <% f.labeled_input: name ,: id = & gt; "Pre_negotiation_value_div",: class = & gt; "Type-Text"% & gt; & Lt;% = f.label: name% & gt; & Lt;% = f.text_field: name% & gt; & Lt;% end% & gt;

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
