我check_box_tag
在尝试在表中搜索存档项目时遇到问题。
<%= hidden_field :archive, :value => false %>
<% if current_user.try(:admin?) %>
Archive: <%= check_box_tag :archive, true, false, :class => "archive" %></H2>
<% else %>
<%= hidden_field :archive, :value => false %>
<% end %>
因此,如果用户不是管理员,则存档总是错误的。
如果用户是管理员,则存档始终为 false,除非他们选中该复选框。
选中该复选框并提交搜索时,将显示结果,但该框再次变为未选中状态。有没有办法检查它检查?我尝试使用:selection => params[:archive]
,但这似乎不起作用。提前致谢。
添加搜索功能
def self.like(text); "%#{text}%"; end
def self.search(search_archive, search_client)
_projects = Project.scoped
if search_archive.present?
_projects = _projects.where(:archive => search_archive)
end
if search_client.present?
_projects = _projects.where ['client LIKE ?', like(search_client)]
end
_projects
end
end
搜索动作:
def search
@search = params[:archive], params[:client]
@project_search = Project.search(*@search).order(sort_column + ' ' + sort_direction).paginated_for_index(per_page, page)
@search_performed = !@search.reject! { |c| c.blank? }.empty?
@project = Project.new(params[:project])
respond_to do |format|
format.html # search.html.erb
format.json { render :json => @project }
end
end
网址:
当我搜索 Client: Test 时,已存档检查:
http://localhost:3000/search?utf8=%E2%9C%93&%5Bclient%5D=Test&%5D=&archive=true&per_page=10
没有找到正确的项目,现在我取消点击存档:
http://localhost:3000/search?utf8=%E2%9C%93&%5Bclient%5D=Test&%5D=&archive%5B%7B%3Avalue%3D%3Efalse%7D%5D=&per_page=10
这再次显示了正确的结果,但该框现在已选中,但应该取消选中,以防我想优化搜索
修复: 在我的搜索功能中:
if search_archive.present?
_projects = _projects.where(:archive => search_archive == "true")
end
if !search_archive.present?
_projects = _projects.where(:archive => search_archive == "false")
end
在我的搜索视图中:
<% if current_user.try(:admin?) %>
Archive: <%= check_box_tag :archive, true, !!params[:archive], :class => "archive" %></H2>
<% end %>
