Question

如果我尝试添加评论或喜欢配方，我会收到错误错误调用方法＆＃39; addReview＆＃39;：内部服务器错误[500] debug.js：41 ，即使它将评论和喜欢添加到数据库中并且工作正常，但仍然让我犯了错误。

源代码Github

add_review.js

Meteor.methods({
    addReview:function(rating,review,recipeId){
        if(review!=""){
            Reviews.insert({
                rating:rating,
                review:review,
                recipeId:recipeId
            });
            Router.go('reviews',{_id:recipeId});

            FlashMessages.sendSuccess('Review Added',{ autoHide: true, hideDelay: 2000 });
        }
        else{
            FlashMessages.sendError('Review field is empty',{ autoHide: true, hideDelay: 3000 });
        }
        return false;
    },
    upvote:function(currentRecipe){


        var user = Meteor.user();
        if(!user){
            FlashMessages.sendError("You need to login to like this recipe", {hideDelay: 1000});

        }
        if (currentRecipe) {
            if (_.contains(currentRecipe.voters, Meteor.userId())) {
                FlashMessages.sendError("You already liked this recipe", {hideDelay: 1000});
                return false;
            }
            Recipes.update(currentRecipe._id, {$addToSet: {voters: Meteor.userId()}, $inc: {likes: 1}});
        }
    }
})

您似乎正在尝试使用不需要的方法，只会让事情变得更难。这不仅仅是客户端代码吗？如果是这样，你可以使用函数：

<强> add_review.js

Template.add_review.events({
    'submit .add-review':function(event){
        event.preventDefault();
        var rating = event.target.rating.value;
        var review = event.target.review.value;
        var recipeId = Router.current().data()._id;
        addReview(rating,review,recipeId);
    }
});
Template.recipes.events({
    "click [data-action='addLikes']": function (event) {
        event.preventDefault();
        var recipe = Recipes.findOne({_id: this._id});
        upvote(recipe)
    }
});

<强>的客户机/ methods.js

addReview = function(rating,review,recipeId){
        if(review!=""){
            Reviews.insert({
                rating:rating,
                review:review,
                recipeId:recipeId
            });
            Router.go('reviews',{_id:recipeId});

            FlashMessages.sendSuccess('Review Added',{ autoHide: true, hideDelay: 2000 });
        }
        else{
            FlashMessages.sendError('Review field is empty',{ autoHide: true, hideDelay: 3000 });
        }
        return false;
    };

 upvote = function(currentRecipe){

        var user = Meteor.user();
        if(!user){
            FlashMessages.sendError("You need to login to like this recipe", {hideDelay: 1000});

        }
        if (currentRecipe) {
            if (_.contains(currentRecipe.voters, Meteor.userId())) {
                FlashMessages.sendError("You already liked this recipe", {hideDelay: 1000});
                return false;
            }
            Recipes.update(currentRecipe._id, {$addToSet: {voters: Meteor.userId()}, $inc: {likes: 1}});
        }
    };

@Waqar首先，在您的methods.js文件中，就像其他人已经告诉过你应该进入/ lib文件夹一样，你应该在你的函数名称周围加上单引号。我已经为Meteor.methods和下面的Template.add-review.events重新编写了代码

client / templates / reviews / add_review.js（抱歉，我把每个模板和js文件放在一个单独的文件夹中）

＆＃13;

Template.add_review.events({
    'submit .add-review': function(event){
        var rating = event.target.rating.value;
        var review = event.target.review.value;
        var recipeId = this._id;
        
        var params = {
            rating: rating,
            review: review,
            _id: recipeId
        }
        
        Meteor.call('addReview', params);
        
        FlashMessages.sendSuccess('Review Added'); // and any other options you want to include 
        Router.go('reviews',{_id:recipeId});
        
        return false;
    }
});

＆＃13;

/lib/methods.js

＆＃13;

Meteor.methods({
    'addReview': function(params){
        Reviews.insert(params);
    }
});

＆＃13;

尝试一下，看看它是否有效。另外，将您的methods.js文件放在/ lib文件夹中，如Stephen建议的那样。
