我想通過http
和post
方法使用rails for server和post數據,然後將數據保存到數據庫。爲此,我有2個模型和控制器:bolouk
和'radif'。 我有關聯如下:Rails關聯:在創建操作中保存方法的類型無效
models/bolouk.rb
:
class Bolouk < ActiveRecord::Base
has_many :radifs, :dependent => :destroy
end
models/radif.rb
:
class Radif < ActiveRecord::Base
belongs_to :bolouk
end
我可以創建新的bolouk
,但是當我想創造新的radif
,我送,我需要爲所有的方法在數據庫中創建新的radif(如bolouk_id
和radif參數),並且我在rails服務器和create action
中收到了這些數據,但是當我想創建新方法時, 500 Internal Error
。
controller/api/v1/radifs_controller.rb
:
class Api::V1::RadifsController < Api::V1::BaseController
def create
@radif = Radif.create(radif_params)
if @radif.valid?
puts "if"
respond_with @radif, :location => api_bolouk_radifs_path
else
puts "else"
respond_with @radif.errors, :location => api_bolouks_radifs_path
end
end
private
def radif_params
params.require(:radif).permit(:bolouk_id, :describe, :price)
end
end
我把一些日誌中創建行動,我定義控制器檢測@radif
爲invalid
,不保存@radif
數據庫。我把服務器日誌如下:
Started POST "/api/bolouks/23/radifs?describe=110&price=128" for 127.0.0.1 at 2014-09-03 16:05:37 +0430
Processing by Api::V1::RadifsController#create as JSON
Parameters: {"bolouk_id"=>"23", "describe"=>"110", "price"=>"128", "radif"=>{"bolouk_id"=>"23"}}

(0.0ms) begin transaction
(0.0ms) rollback transaction
else
Completed 500 Internal Server Error in 27ms (Views: 1.0ms | ActiveRecord: 1.0ms)
我發送來自angularjs數據,我有下面的代碼: newradif.html
:
<form ng-submit="saveRadif()" class="form-horizontal" role="form">
<div>
<ul>
<li ng-repeat="err in errors">{{err}}</li>
</ul>
</div>
<div class="form-group">
<label for="radifdescribe" class="col-sm-2 control-label"><span>Describe:</span></label>
<div class="col-sm-4">
<input ng-model='modalRadif.describe' class="form-control" id="radifdescribe" placeholder="describe">
</div>
</div>
<div class="form-group">
<label for="radifprice" class="col-sm-2 control-label"><span>Price</span></label>
<div class="col-sm-4">
<input ng-model="modalRadif.price" class="form-control" id="radifprice" placeholder="price">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-success">Create</button>
</div>
</div>
</form>
和angularjs控制器:
$scope.saveRadif = function(){
Radifs.create($scope.modalRadif, {bolouk_id: $scope.saveBolouk.id}).$promise.then(function(data){
$scope.radifs = Radifs.index({bolouk_id: $scope.saveBolouk.id});
// $scope.saveRadif = data;
})
.catch(function (err) {
console.log(err.data);
})
}
app.factory('Radifs', function($resource) {
return $resource('/api/bolouks/:bolouk_id/radifs', {bolouk_id: '@bolouk_id'}, {
index: { method: 'GET', isArray: true},
create: { method: 'POST' }
});
});
我怎樣才能解決這個問題?
您的描述和價格超出了參數中的radif散列值。你可以展示你的表單嗎?你也需要調用save方法而不是create方法。 – Mandeep 2014-09-03 11:55:50
我將表單添加到問題中。 – mgh 2014-09-03 12:03:33
@Mandeep你的指導是非常有用的。我檢查表單並編輯數據發送的類型。 – mgh 2014-09-03 20:47:09
