我正在使用Javascript更改表单标签并为其赋予新的操作字符串。但是从我所看到的一切来看，操作字符串是正确的。但是，Rails给了我一个路由错误。寻找另一双眼睛...

事实证明，使用Rails路由，当您要更新模型时，表单标签显示method =“ post”，但还有一个附加标签：<input name="_method" type="hidden" value="patch" />如果没有，确实会得到所示的路由错误。因此，正确的方法是：
<form data-target="content.modalForm" action="/contents/1" accept-charset="UTF-8" method="post">
<input name="utf8" type="hidden" value="✓"><input type="hidden" name="authenticity_token" value="XUQvzwi2ciBJTFanlHlhGrYPEYfHu/O+oziHQy6r6iAcF0630KuccE2I0ct4Le6MC95pQEu/uconVCS19MwmaA==">
<div class="field">
<label class="label" for="content_text">Enter Original Text</label>
<div class="control">
<textarea class="textarea" name="content[text]" id="content_text"></textarea>
</div>
</div>
<div class="field">
<label class="label" for="content_from_lang">Language of original</label>
<div class="select">
<select name="content[from_lang]" id="content_from_lang"><option value="en">English</option>
<option value="fr">French</option>
<option value="es">Spanish</option>
<option value="nl">Dutch</option>
<option value="ar">Arabic</option>
<option value="is">Icelandic</option>
<option value="ja">Japanese</option>
<option value="it">Italian</option>
<option value="iw">Hebrew</option></select>
</div>

</form>

您的操作中具有get方法时，表单中的方法名称将为post。
