[英]Rails 4 - Ajax form adding a new record instead of editing the current record
[英]Rails 4 nested attributes not adding record to current project, instead it's adding new project records
項目更新中的記錄將被上載到新的項目記錄中。
我正在嘗試使用cocoon gem作為嵌套屬性,但是它添加了新的項目記錄,而不僅僅是在同一項目中添加了新的項目更新
我在/views/projects/show.html.haml中有此表格
= form_for @pu do |f|
#updates
= f.simple_fields_for :project_updates do |u|
= render 'update_fields', f: u
.links
= link_to_add_association 'add updates', f, :project_updates, class: "button"
= f.submit "Submit updates", class: "button"
然后在我的projects_controller.rb中
def show
@pu = Project.new
end
def create
@project = Project.new(project_params)
respond_to do |format|
if @project.save
format.html { redirect_to @project, notice: 'Project was successfully created.' }
format.json { render :show, status: :created, location: @project }
else
format.html { render :new }
format.json { render json: @project.errors, status: :unprocessable_entity }
end
end
end
private
def project_params
params.require(:project).permit(:name, :address, :client, :budget,
project_updates_attributes: [:updates, :notes, :done, :impact_schedule, :impact_budget, :_destroy])
end
如果可能,我想在同一項目中不斷添加記錄
編輯,添加編輯和更新
def edit
end
def update
respond_to do |format|
if @project.update(project_params)
format.html { redirect_to @project, notice: 'Project was successfully updated.' }
format.json { render :show, status: :ok, location: @project }
else
format.html { render :edit }
format.json { render json: @project.errors, status: :unprocessable_entity }
end
end
end
只是標准的編輯和更新支架。
仍然存在在顯示頁面(項目顯示頁面)內應用嵌套屬性(窗體)的問題,並且當嘗試在項目中添加新任務時,它會添加新項目記錄並將該任務包括在該新項目中,而不是更新當前項目中的任務。 如果可以幫助重寫我所修復的內容,將不勝感激。
編輯:
根據幫助,結果如下:
添加了狀態1(單擊“提交更新”),但是,當我刷新頁面時,將顯示“狀態1”輸入字段,然后當我嘗試添加另一個更新(狀態2)時,將填充原始狀態1(除了新更新),因此將不斷添加以前添加的記錄。 我只希望此顯示頁面僅將新更新添加到記錄中,而不在輸入字段中顯示現有記錄。
編輯2:
顯示頁面中的新表格,必須按照以下建議的答案消除url
,因為它沒有給我路由錯誤
= simple_form_for @project do |f|
#updates
= f.simple_fields_for :project_updates do |u|
= render 'project_update_fields', f: u
.links
= link_to_add_association 'add updates', f, :project_updates, class: "button"
= f.submit "Submit updates", class: "button"
_project_update_fields.haml部分
.nested-fields
= f.input :updates, placeholder: "Updates", label: false
.small-2.column
= f.input :impact_budget, as: :boolean
.small-2.column
= f.input :impact_schedule
.small-12.column
= link_to_remove_association "remove task", f, class: "button"
幾乎沒有要處理的問題。
首先也是最重要的是:
def show
# instantiating new project_update is not even needed, nested_attributes will do that for you
@pu = Project.new
end
為了能夠更新現有項目,您需要執行以下操作:
# change the show so that it finds the project which are at now:
def show
# find a project we want to add updates to
@project = Project.find(params[:id])
end
# edit the form a bit
= form_for(@project, url: projects_path(@pu)) do |f| # <===, not nessecary though. Should work as you have it as well
#updates
= f.simple_fields_for :project_updates do |u|
= render 'update_fields', f: u
要僅創建新更新(而不在項目的編輯表單上顯示現有更新),請執行以下操作:
# making sure, that simple_fields_for are only displayed for new update object's creation
- if f.object.new_record?
.nested-fields
= f.input :updates, placeholder: "Updates", label: false
.small-2.column
= f.input :impact_budget, as: :boolean
.small-2.column
= f.input :impact_schedule
.small-12.column
= link_to_remove_association "remove task", f, class: "button"
首先,您需要將操作拆分為創建和更新。 這樣,您可以更新現有記錄。
您的更新操作將非常相似,但是
@project = Project.new(...)
它會像
@project = Project.find(params[:project_id])
另外,您將需要調用@project.update_attributes(project_params)
而不是@project.save
祝您好運。 如果您有任何問題,請詢問。
