Mongoose model 'error' event fired on 'Post' with error:
next is not a function TypeError: next is not a function

why

tsuNammi

@tsuNammi

so I have <title><%= data.post.title %></title> in my header-partial for everything. if u visit /post/something_that_doesn't_exist

I get an error : Cannot read property 'title' of null

bc data.post doesn't exist obviously

I've been encountered with the error handler with flash-message view render issue. the error object from getUpdateHandler(req).process({fileds: validator}) is quite different than the error message from req.flash('error', msg) and gives the views a different object to render. using conditional statement could solve it , any solution from your guys? or Did I do it in the wrong way?

// Error from getUpdatehandler
{ info: [],
  success: [],
  warning: [],
  error:
   [ { type: 'ValidationError',
       title: 'There was a problem saving your changes',
       list: [Array] },
     'Password must be longer than 8 characters.' ] }

// Error from req.flash
{ info: [],
  success: [],
  warning: [],
  error: ['Password must be longer than 8 characters.' ] }

@tsuNammi you can get locals.section = 'info' in view directly , no need to use jQuery. the key of section is available in the view.

explanation in UI, you could useLists > Options > labelapi and next should nothing to do with Mongoose, it is express middleware function. hope it could help you.

UI was good, I just used notes for each field, kinda hard to find anything about it in the documentation though

hmm, oh so you mean I can get the title of each post in the route file

and set it instead of in the actual render file

that's not stupid

I'll try

tried

view.render('post', {title: locals.data.post.title});

didn't work dude

TypeError: Cannot read property 'title' of undefined

@tsuNammi

trying to do:

// Load the current post
view.on('init', function (next) {

    var q = keystone.list('Post').model.findOne({
        state: 'published',
        slug: locals.filters.post,
    });

    q.exec(function (err, result) {
        locals.data.post= result;
        console.log(result);
        title: locals.data.post.title;
        next(err);
    });

});

then

view.render('post');

but does not work

Hi, @tsuNammi, locals object is the object will pass down to your view. so if you want to load the title from view. you need make sure the key of 'title' nested the locals object directly.

view.on('init', function (next) {

    var q = keystone.list('Post').model.findOne({
        state: 'published',
        slug: locals.filters.post,
    });

    q.exec(function (err, result) {
        locals.data.post= result;
        /* Try this */
        locals.title: locals.data.post.title
        console.log("Locals: ", locals)
        console.log("Locals > Title: ", locals.title)
        next(err);
    });

});

Yes, keystoneJS need some helps for their documents. it is missing some of explanation for the APIs which is very important in build. Check out this site, http://keystonejs.netlify.com/guides, it did helped me somehow,

and this post https://groups.google.com/forum/#!topic/keystonejs/fZ9tqrlpkFI

the above link explained why use view.on('init') over view.on('get') in indirect way. 🤔

@tsuNammi

thanks man, but I guess I've already handled it with if/else statements in the headerpartial file. it's not nice and clean, but I figured if ppl went to a /post/id-that-does-not-exist, the only problem wouldn't just be the title

there's a lot of stuff in the post-template that would need to access a data.post which does not exist, and I can't handle them cleanly at the same time

doesn't matter anyways

I just send them to a 404/500 error default page instead handling all the errorenous database calls for an object that doesn't exist with if/else before actually making a default template with 'post not found'

unless anyone else has a better idea when ppl try to access a post/'slug' that does not exist

Hi All, is there a way to detect if data has come from an update in a model? basically I want to add a mongoose post hook that only triggers from admin ui saves and not updates.

@sordfish

woo @JedWatson is back

@max8hine_twitter

@sordfish have you tried the getUpdateHandler API from keystone? that API could help me to modify the data before update the model.

@tsuNammi

so I tried deploying today

ran into a reaaaally weird problem

I have <strong> tags all over when I "inspect" using Chrome Inspector

they don't appear when I "view page source"

it's messing up my front end

I have no idea where to begin

it has something to do with the text that I've fetched from MongoDB

maaaybe because I have some a tags and strong tags entered into the content in the MongoDB

it appears normal when I access mongo shell and look at the objects

or it started when I started filling in stuff with a/strong tags in I think

but I have the same code running on cloud9

and no problems there

tried downgrading node versions to match cloud9's
