simple_form 'form-inline' not working

问题:

I'm trying to make two input (firstname and lastname) to next to each other.

Here is my code and it's currently just showing two big rows of input window.

= simple_form_for @user, html: {class: 'form-inline'} do |f|
  = f.fields_for :profile, @user.profile || Profile.new, html: {class: 'form-inline'}  do |p|
     .form-1
        .form-1-detail
           .input-text
              = f.input :last_name, required: true
           .input-text
               = f.input :first_name, required: true

I'm now sure how to make them to display inline. Can anyone help me?

Thanks!

Updated. This is the actual HTML generate from

= simple_form_for @user, html: {class: 'form-inline'} do |f|
 = f.fields_for :profile, @user.profile || Profile.new do |p| # removed form-inline here
  .form-1
    .form-1-detail
      .form-group
        = f.input :last_name, required: true
      .form-group
        = f.input :first_name, required: true




</div><form class="simple_form form-inline" novalidate="novalidate" id="new_user" action="/users" accept-charset="UTF-8" method="post"><input name="utf8" type="hidden" value="&#x2713;" /><input type="hidden" name="authenticity_token" value="DhQSodBk8kxdE6q9uPJDKSs9FfxCNLyXFYT3bZ42HlZfHefxfG3BDq9qkFpxkX7MBZI4Mc4Wje6LKw7Gp1YcjQ==" />
  <div class="form-1">
    <div class="form-1-detail">
      <div class="form-group">
        <div class="input string required user_last_name"><label class="string required" for="user_last_name"><abbr title="required">*</abbr> 姓</label><input class="string required" placeholder="姓" type="text" name="user[last_name]" id="user_last_name" /></div>
      </div>
      <div class="form-group">
        <div class="input string required user_first_name"><label class="string required" for="user_first_name"><abbr title="required">*</abbr> 名</label><input class="string required" placeholder="名" type="text" name="user[first_name]" id="user_first_name" /></div>
      </div>
    </div>
  </div></form>

You should install the simple_form wrappers:

rails generate simple_form:install --bootstrap

From there you can structure a inline_form using it's corresponding wrapper:

simple_form_for @user, wrapper: :inline_form, html: { class: 'form-inline' } ...

They have an example app: https://github.com/rafaelfranca/simple_form-bootstrap

The specific view that using this is (sorry it's ERB however):

回答2:

Try using f.input_field instead of f.input.

The simple_form gem uses Bootstrap, right? I compared your code to the Bootstrap Form docs and I think you should be using form-group classes inside the form-inline.

= simple_form_for @user, html: {class: 'form-inline'} do |f|
  = f.fields_for :profile, @user.profile || Profile.new do |p| # removed form-inline here
   .form-1
      .form-1-detail
         .form-group
            = f.input :last_name, required: true
         .form-group
            = f.input :first_name, required: true

Alternatively, unless you have unique CSS that you need to apply for the form-1 and form-1-detail classes, this might be able to be shortened to:

= simple_form_for @user, html: {class: 'form-inline'} do |f|
  = f.fields_for :profile, @user.profile || Profile.new do |p| # removed form-inline here
     .form-group
        = f.input :last_name, required: true
     .form-group
        = f.input :first_name, required: true

If that doesn't work, can you post the actual HTML that is generated for the form in the browser?
