Rails Simpleform与非模型输入 [英] Rails Simpleform with non-model inputs
问题描述
我有一个使用simpleform的正常表单。现在我想添加一个在模型中没有任何相应字段的输入,它将由控制器处理。我试过
<%= simple_form_for @obj do | f | %GT;
<%= f.input:name%>
<%= f.input:attr,as::string%> < - 只应发送attr作为发布数据
<%end%>>
但是这给出了一个未找到方法:attr_not_in_obj
错误。我明显可以使用标准的rails助手,但是我会忽略输入周围的所有简单HTML,并且复制看起来不太合适。
简而言之:
我正在寻找类似于rails标签助手的简单版本,但没有任何与模型的连接。如何添加不符合模型属性的输入?
为什么不添加:
attr_accessor:attr
添加到模型的类定义中吗?这样你的代码:
<%= f.input:attr%>
应该有效。
OR
如果此解决方案不合适,您可以随时将一些值传递给输入
直接使用方法:
<%= f.input:attr,input_html:{value:'something'}%>
I have a normal form using simpleform. Now I'd like to add an input that does not have any corresponding field in the model, it will be processed by the controller. I tried
<%= simple_form_for @obj do |f| %>
<%= f.input :name %>
<%= f.input :attr, as: :string %> <-- should just send "attr" as post data
<% end %>
but this gives a Method not found: attr_not_in_obj
error. I could obviously use the standard rails helpers, but then I will miss all of the simpleform HTML around the input, and copying doesn't quite seem right.
In short: I'm looking for something like simpleform version of rails tag helpers, without any connection to a model. How do I add inputs that do not correspond to model attributes?
Why don't you add:
attr_accessor :attr
to your model's class definition? This way your code:
<%= f.input :attr %>
should work.
OR
If this solution isn't suitable, you can always pass some value to your input
method directly:
<%= f.input :attr, input_html: {value: 'something'} %>
