我需要有关错误验证/重定向的帮助。...
如果我使用format.html {redirect_to :back, flash: {error: "Oops, something went wrong. Please try again."}
,则错误消息有效,但是它不包含表单数据,因此用户需要重新输入并且不知道哪些字段不正确。format.xml {render :xml => @award.errors, :status => :unprocessable_entity}
行重定向到back,但不显示任何错误。
我想查看哪些字段不正确,且其验证消息完整无缺。请帮助语法。提前致谢!
respond_to do |format|
if @award.save
format.html { redirect_to(new_award_path, :notice => 'Thank you for your nomination!') }
format.xml { render :xml => @award, :status => :created, :location => @award }
else
format.html {redirect_to :back}
#format.html {redirect_to :back, flash: {error: "Oops, something went wrong. Please try again."}}
format.xml {render :xml => @award.errors, :status => :unprocessable_entity}
end
end
更新以包括更多详细信息:
我为此创建方法使用了2种不同的形式。每个表单都有一个用于设置 bool(boolean) 值的隐藏字段,然后我根据该隐藏条件在 Controller 中进行操作。如果有错误,我需要重定向到正确的表单,保留其值,并显示适当的错误字段。像这样:
respond_to do |format|
if @award.save
format.html { redirect_to(new_award_path, :notice => 'Thank you for your nomination!') }
format.xml { render :xml => @award, :status => :created, :location => @award }
else
if boolean_field == true
format.html { render action: "true_form" }
format.xml {render :xml => @award.errors, :status => :unprocessable_entity}
else
format.html { render action: "false_form" }
format.xml {render :xml => @award.errors, :status => :unprocessable_entity}
end
end
end
当我以这种方式尝试时,错误会起作用,但是即使我从false_form开始,也总是返回true_form。因此,这就像忽略了boolean_field条件...有意义吗?
最佳答案
诀窍不是在出现错误时重定向,而只是再次渲染 View 。
respond_to do |format|
if @award.save
format.html { redirect_to(new_award_path, notice: 'Thank you for your nomination!') }
format.xml { render xml: @award, status: :created, location: @award }
else
format.html { render action: 'new' }
format.xml { render json: @award.errors, status: :unprocessable_entity }
end
end
