転置配列

• .zip
• .transpose

# .zip
[A,B].zip([hoge,fuga])      #=> [[A,hoge], [B,fuga]]
[A,B].zip([hoge,fuga]).to_h #=> { A=>hoge,  B=>fuga}

Thinreports_Editor用 の 転置配列. 引数はどちらも配列状態でもらう。key部分は、可変長引数で羅列で第2引数でもらう。

# .transpose
def replaceArray(valAry, *keyAry)
  newAry = [keyAry,valAry].transpose
  h = Hash[*newAry.flatten]            #[A,B],[hoge,fuga] => [A=>hoge, B=>fuga]
end

radioBox 単数選択と排他選択

<%  # .erb
    ryuijikou2_3_data= ["装置","使用機器","管理"]
    ryuijikou2_3_data.each do |v|
    p params[:ryuijikou2_3]
%>
    <%= f.radio_button :ryuijikou2_3, "#{v}" %>
    <label for="ccnumber"><%= v %></label>
<% end %>

# pdf Thinreports_Editor
ryuijikou_data = {"ryuijikou2_3a"=>"装置","ryuijikou2_3b"=>"使用機器","ryuijikou2_3c"=>"管理"}
ryuijikou_data.each do |k,v|
  if v == report["ryuijikou2_3"]
    page.item(k)
  else
    page.item(k).hide
  end
end

Validation

Error Display

check debug

#controller
def hoge
  render plain: report.errors.inspect
end

「Rails5 バリデーションエラー URL変わる」は仕様? 回答参照
Reloadするとエラーになる時の解決方法
解決： JavaScriptの力技

# view
<% if post.errors.any? %>
  <script type="text/javascript">
    $(document).ready(function() {
      history.pushState('', '', location.href + '/new')
    });
  </script>
  
  # パラメーターが変動する場合: ?id=2 など
  <script type="text/javascript">
      $(document).ready(function() {
          history.pushState('', '', location.href + '/new' + document.referrer.split("new")[1] )
      });
  </script>  
<% end %>

render

# controller
render :edit

# view
<% if @hoge.errors.messages[:end_date].present? %>
    <div class="alert alert-danger alert-dismissible fade show" role="alert">
        <%= @hoge.errors.messages[:end_date][0] %>
    </div>
<% end %>

if URL changes and loses the /edit. when it reload ERROR.
http://localhost:3000/preferences/1/edit
http://localhost:3000/preferences/1

redirect_to !保存されたり、APIにpatchは投げるみたい。。

# controller v1
def update
..
  flash[:notice] = "error!!" 
  redirect_to :action => :edit
end

# controller v2
def update
  report = Hoge.new(hoge_params)
..
  flash[:notice] = report.errors.messages[:end_date][0]
  redirect_to action: :edit
end

#view
<%= flash[:notice] %>

#bootstrap version1
<% if flash[:notice] %>
    <div class="alert alert-danger alert-dismissible fade show" role="alert">
        <%= flash[:notice] %>
    </div>                                      
<% end %>
#v2
<% if @foo.errors.messages[:end_date].present? %>
    <div class="alert alert-danger alert-dismissible fade show" role="alert">
        <%= @foo.errors.messages[:end_date][0] %>
    </div>
<% end %>
