[英]Bootstrap on rails form helper issue with date_field and select
I'm trying to style my form in rails with bootstrap-4. 我正在尝试使用bootstrap-4在表单中设置表单的样式。 But I'm having issues apply styles to the date_field helper and the select helper. 但是我在将样式应用于date_field助手和选择助手时遇到了问题。
This is the date field. 这是日期字段。 The class won't apply and throws an error until I take it off. 直到我将其取消,该课程才适用,并引发错误。
<div class="form-group row">
<%= form.label :appointment, :class => 'col-md-3 col-form-label text-md-right' %>
<div class="col-md-9">
<%= date_field(:patient, :apointment), :class => 'form-control' %>
</div>
</div>
This is the select helper. 这是选择助手。 The options are appearing outside of the select box. 选项显示在选择框之外。
<div class="form-group row">
<%= form.label :consultationType, :class => "col-md-3 col-form-label text-md-right" %>
<div class="col-md-9">
<select class ="form-control">
<!--Gets all counties from DB -->
<%= form.select :consultationType,
[
"N/A",
"Inhouse-Clinic",
"St.James Hospital - X-Ray",
"Matter Private Dublin - Cardiology",
"Matter Private Cork - Neurology",
"Royal Eye and Ear - Ophthalmology",
"Temple Street - Children"
]
%>
</select>
</div>
</div>
Try to the following 尝试以下
<%= date_field(:patient, :apointment, class: "form-control") %>
Generated HTML 生成的HTML
<input class="form-control" type="date" name="patient[apointment]" id="patient_apointment">
And for the select tag, you have declared two times, you can remove the HTML <select>
tag and then add the bootstrap class like this 对于select标记,您已经声明了两次,可以删除HTML <select>
标记,然后添加如下所示的bootstrap类
<%= form.select :consultationType,
[
"N/A",
"Inhouse-Clinic",
"St.James Hospital - X-Ray",
"Matter Private Dublin - Cardiology",
"Matter Private Cork - Neurology",
"Royal Eye and Ear - Ophthalmology",
"Temple Street - Children"
], {}, {class: "form-control"}
%>
Generated HTML like this 这样生成的HTML
<select class="form-control" name="patient[consultationType]" id="model_consultationType"><option value="N/A">N/A</option>
<option value="Inhouse-Clinic">Inhouse-Clinic</option>
<option value="St.James Hospital - X-Ray">St.James Hospital - X-Ray</option>
<option value="Matter Private Dublin - Cardiology">Matter Private Dublin - Cardiology</option>
<option value="Matter Private Cork - Neurology">Matter Private Cork - Neurology</option>
<option value="Royal Eye and Ear - Ophthalmology">Royal Eye and Ear - Ophthalmology</option>
<option value="Temple Street - Children">Temple Street - Children</option>
</select>
For the date_field
move the class inside the brackets: 对于date_field
请将类移到方括号内:
date_field(:patient, :appointment, class: 'form-control')
And for the select
it is not required to give HTML select tag explicitly. 对于select
,不需要显式提供HTML select标签。 Just doing like this will do the job: 只需执行以下操作即可:
<%= form.select :consultationType, ["N/A", "Inhouse-Clinic", "St.James Hospital - X-Ray", "Matter Private Dublin - Cardiology", "Matter Private Cork - Neurology", "Royal Eye and Ear - Ophthalmology", "Temple Street - Children"], {}, { class: 'form-control' } %>
