我正在使用Rails 7创建一个名为雇员管理系统的应用程序。要添加员工,我已经创建了一个表单。在这里,我已经使用嵌套表单字段gem添加了雇员的联系人。问题是,当第一次加载表单时,当我想添加或删除联系人字段时,它将重定向到相同的窗体。但是当我刷新页面时,它就开始工作了,没有任何问题。即使添加或删除的字段也会反映在数据库中。它只在第一次加载“创建或更新员工”页面时创建此问题。我所发现的是,当我单击该链接以添加员工并打开表单时。事件没有在html中加载。正如我们在下面的图片中看到的身体标签:

但是在刷新之后,事件将被加载:

我在gem文件夹中看到过js.coffee文件,但是对于像我这样的初学者来说,这太高级了。代码如下所示:
window.nested_form_fields or= {}
nested_form_fields.bind_nested_forms_links = () ->
$('body').off("click", '.add_nested_fields_link')
$('body').on 'click', '.add_nested_fields_link', (event, additional_data) ->
$link = $(this)
object_class = $link.data('object-class')
association_path = $link.data('association-path')
added_index = $(".nested_#{association_path}").length
$.event.trigger("fields_adding.nested_form_fields",{object_class: object_class, added_index: added_index, association_path: association_path, additional_data: additional_data});
if $link.data('scope')
$template = $("#{$link.data('scope')} ##{association_path}_template")
else
$template = $("##{association_path}_template")
target = $link.data('insert-into')
template_html = $template.html()
# insert association indexes
index_placeholder = "__#{association_path}_index__"
template_html = template_html.replace(new RegExp(index_placeholder,"g"), added_index)
# look for replacements in user defined code and substitute with the index
template_html = template_html.replace(new RegExp("__nested_field_for_replace_with_index__","g"), added_index)
# replace child template div tags with script tags to avoid form submission of templates
$parsed_template = $(template_html)
$child_templates = $parsed_template.closestChild('.form_template')
$child_templates.each () ->
$child = $(this)
$child.replaceWith($("<script id='#{$child.attr('id')}' type='text/html' />").html($child.html()))
if target?
$('#' + target).append($parsed_template)
else
$template.before( $parsed_template )
$parsed_template.trigger("fields_added.nested_form_fields", {object_class: object_class, added_index: added_index, association_path: association_path, event: event, additional_data: additional_data});
false
$('body').off("click", '.remove_nested_fields_link')
$('body').on 'click', '.remove_nested_fields_link', ->
$link = $(this)
return false unless $.rails == undefined || $.rails.allowAction($link)
return false if $link.attr('disabled')
object_class = $link.data('object-class')
delete_association_field_name = $link.data('delete-association-field-name')
removed_index = parseInt(delete_association_field_name.match('(\\d+\\]\\[_destroy])')[0].match('\\d+')[0])
$.event.trigger("fields_removing.nested_form_fields",{object_class: object_class, delete_association_field_name: delete_association_field_name, removed_index: removed_index });
$nested_fields_container = $link.parents(".nested_fields").first()
delete_field = $nested_fields_container.find("input[type='hidden'][name='#{delete_association_field_name}']")
if delete_field.length > 0
delete_field.val('1')
else
$nested_fields_container.before "<input type='hidden' name='#{delete_association_field_name}' value='1' />"
$nested_fields_container.hide()
$nested_fields_container.find('input[required]:hidden, select[required]:hidden, textarea[required]:hidden').removeAttr('required')
$nested_fields_container.trigger("fields_removed.nested_form_fields",{object_class: object_class, delete_association_field_name: delete_association_field_name, removed_index: removed_index});
false

有什么东西可以改变来解决这个问题吗?救命啊!!

在我的应用程序开发了两天之后,当我在application.js中添加一个使永久地址和本地地址相同的复选框时,同样的问题出现了。因此,我得出结论,这个问题并不是因为创业板,而是其他一些原因。所以我在谷歌上搜索了一下,发现涡轮键是罪魁祸首。在turbo中搜索之后,github存储库发现了“关闭”类别中的问题。通过在application.html.erb中给我的头部分添加一条简单的行,就可以读到这个问题。这一行是:
<meta name="turbo-visit-control" content="reload">不过,有个问题。添加此行后,闪存消息由于重新加载而消失。所以我又谷歌了一遍,想找出一个更好的方法。删除这一行,并在application.js中更改
import "@hotwired/turbo-rails"至
import { Turbo } from "@hotwired/turbo-rails"
Turbo.session.drive = false`这是我在turbo readme.md中发现的。闪存消息重新出现,不需要刷新页面。
