rails simple_nested_form_for fields_for wrong number of arguments

由 时间秒杀一切 提交于 2019-12-08 16:37:43
问题 So I'm building a form in rails 3.1, using <%= simple_nested_form_for(@person, :url => collection_url, :html=>{:multipart => true}) do |f| %> <%= render :partial => "form", :locals => { :f => f } %> <% end %> but this line in the partial is causing the problem: <h2>Badges</h2> <ul id="certifications"> // this following line is raising the error "wrong number of arguments (4 for 3)" <%= f.fields_for :certifications do |certification_form| %> <%= render :partial => 'certification', :locals => {

Rails form_tag form writing - with non-active record model

由 ♀尐吖头ヾ 提交于 2019-12-08 16:29:35
问题 I'm somewhat of a Rails newbie. I'm writing a couchrest-rails app, so am not using activerecord for this model. I just figured out that that means that form_for(@model) won't work. I'm trying to work out how to use form_tag -- but most of the examples don't involve new & create actions. This is wrong: <h1>New article</h1> <% form_tag new_article_url(@article), :method => :post do |f| %> <%= f.error_messages %> <p> <%= f.label :title %><br /> <%= f.text_field :title %> </p> <p> <%= f.submit

Rails XML builder with no pretty-printing (i.e. minified XML)

由 一世执手 提交于 2019-12-07 15:52:16
问题 I am using Builder::XmlMarkup to produce data structures in XML format for a RESTful API server. Recently, I discovered a bug where the pretty-printing from Builder::XmlMarkup produced an element full of whitespace text instead of an empty element as it should. For example, this code: xml.outertag do xml.list do # Some code which loops through a list end end is producing: <outertag> <list> </list> </outertag> When the inner list is an empty list, the element must be empty—i.e. <list/> or

Give a 404 instead of a 500 error for missing templates

由 烂漫一生 提交于 2019-12-07 07:38:49
问题 I have a Rails 3.0 app (working on a 3.2 upgrade) and whenever someone requests a template that doesn't exist it gives a 500 error in production. For instance mysite.com/blog_posts/532 sends the post with ID 532 back as HTML no problem, but if for some reason mysite.com/blog_posts/532.txt is requested, the app raises a 500 ActionView::MissingTemplate error. This shouldn't happen, because the template shouldn't be there in the first place. It should more properly be a 404 error, or perhaps

How to pass multiple locals to a nested partial

由 倾然丶 夕夏残阳落幕 提交于 2019-12-06 06:24:31
问题 This should be extremely straightforward and well documented, and I've done it several times, although there's something that's still killing me. I have a structure of partials calling nested partials. At some point one render call needs to pass an extra variable to the partial, although the rendering of the partial fails with a: undefined local variable or method `<variable name>' for #<#<Class:....> Here's my code for calling the render : = f.simple_fields_for :orders do |c| = render
