问题描述
我能够成功创建我的 Team 类的新实例,但是每当我在实例上调用 save 时,我都会得到:
undefined method `title' for #<Team:0x00007fddfc7fb570>
这是在我的“team_attributes=”方法中,因此它运行了不包含 :title 方法或属性的强参数。
def created_user_params
params.require(:user).permit(:first_name,:last_name,:email,:password,:password_confirmation,:privilege,position_attributes: [
:title,:description,:team_id,],:team_attributes => [
:name,:id,:profile #for determining if the form came from the profile page. Do not allow into update or create method for team
]
).with_defaults(user_id: current_user.id)
end
这是我的“team_attributes="方法:
def team_attributes=(team_attributes)
self.update(user_id: self.id) if self.user_id.nil?
binding.pry
# selecting a team from a dropBox
if !team_attributes[:id].nil?
@team = Team.find_by(id: team_attributes[:id])
# updating an existing team
elsif self.position && team_attributes[:name]!="" && team_attributes[:profile].nil?
self.team.update(team_attributes.with_defaults(company: self.company,user_id: self.user_id))
@team = self.team
else
# creating a team from the profile page
if team_attributes[:profile] == "profile"
@team = Team.create(name: team_attributes[:name],description: team_attributes[:description],company: self.creator.company,user_id: self.user_id )
# creating a team
elsif team_attributes[:name] != ''
@team = Team.new(team_attributes.except(:profile).with_defaults(company: self.company,user_id: self.user_id))
@team.save
else
end
end
self.update(assigned_position_id: @position.id) if self.position
if @position
@position.update(team_id: @team.id) if @team
end
end
这是创建实例的地方
# creating a team from the profile page
if team_attributes[:profile] == "profile"
@team = Team.create(name: team_attributes[:name],user_id: self.user_id )
我不确定错误来自哪里。您可以从 params 和 method 中看到没有“title”属性。运行“new”创建一个新实例很好,但通过“save”或“create”保存它会引发上面的错误。任何帮助,将不胜感激。谢谢。
