If you have your app with you you could do this in your project directory

    meteor deploy test.meteor.com --delete
    meteor deploy test.meteor.com 

The first deletes the app so its all blank. The second deploys a fresh instance of it back.

one way is to login to the mongo instance yourself and delete the relevant data
so something like per collection:

    $ meteor mongo APP.meteor.com
    &gt; db.users.drop()
    &gt; db.xxx.drop()

you could just drop the whole DB, but that would confuse their env and you have to `--delete` the app and re-deploy anyway.

    &gt; db.dropDatabase()


I know this is a bit old, but I just changed my collection name.  so in your `/lib/collections.js` file,

    someCollection = new Mongo.Collection(&quot;originalcollection&quot;);
becomes

    someCollection = new Mongo.Collection(&quot;newcollectionname&quot;);

this is assuming of course that your app generates the data for the database.  

    

Simply you can access your meteor DB as

&gt; **production-db-d2.meteor.io:27017/XYZ_meteor_com**
&gt; 
&gt; where XYZ = your subdomain

for authentication use meteor auth (username &amp; password)

You can access it from **rockmongo**, **robomogo**, **mongoui**, etc tools.

To access from command line

First authenticate by typing username, password of meteor

&gt; **$ meteor login**

Then

&gt; **$ meteor mongo XYZ.meteor.com**



 

How can I count all characters in a bash variable? For instance, if I had

    &quot;stackoverflow&quot;

the result should be

How can I count the number of characters in a Bash variable

Suppose I have a string like:

    MyString = &quot;OU=Level3,OU=Level2,OU=Level1,DC=domain,DC=com&quot;;

then I want to know how many time of occurrences of sub-string &quot;OU=&quot; in this string. With single char, maybe there is something like:

    int count = MyString.Split(&quot;OU=&quot;).Length - 1;

but `Split` only works for `char`, not `string`.

Also how to find the position of n occurrences? For example, the position of 2nd `&quot;OU=&quot;` in the string?

How to resolve this issue?

Is there a simple way to reset the data from a meteor deployed app?
 
So, for example, if I had deployed an app named `test.meteor.com` — how could I easily reset the data that has been collected by that app?

Locally I run `meteor reset`, but I am unsure of what to do in production.

Meteor app — resetting a deployed app&#39;s DB

Is there a simple way to reset the data from a meteor deployed app?

I have just installed Meteor version 0.5.9 (45fef52095) to my CentOS release 6.3 (Final) server (Linux version 2.6.32-279.19.1.el6.i686 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) ) #1 SMP Wed Dec 19 04:30:58 UTC 2012)

I have a samba share to a Windows SBS server mounted as /mnt/apshared under the apache user. I have created a directory inside this called &#39;webmeteor&#39;. I have created an app called &#39;myapp&#39; inside the &#39;webmeteor&#39; directory, so my directory is like so: /mnt/apshared/webmeteor/myapp.

I am logged in as root. When I try to run the app using the `meteor` command, I am given the following error messages:

    Unexpected mongo exit code 100. Restarting.
    Unexpected mongo exit code 100. Restarting.
    Unexpected mongo exit code 100. Restarting.
    Can&#39;t start mongod

    MongoDB had an unspecified uncaught exception.
    Check to make sure that MongoDB is able to write to its database directory.

My first point of call was this StackOverflow question: https://stackoverflow.com/questions/14496190/creating-a-new-meteor-js-file-and-get-error-100-mongodb-not-able-to-write -- however, following these suggestions (sudo&#39;ing the meteor command, and checking for disk space of which I have 70GB free) has not worked. I am quite certain that these issues are permission related.

I have tried to `chown` recursively to root:root (as I am logged in as root), and `chmod` to 777 recursively also, but to no avail.

I am asking you, what should I try next, to allow my Meteor app to start?

Thanks in advance.

Meteor: unexpected mongo exit code 100

I have this mongoose schema

    var mongoose = require(&#39;mongoose&#39;);
    
    var ContactSchema = module.exports = new mongoose.Schema({
      name: {
        type: String,
        required: true
      },
      phone: {
        type: Number,
        required: true,
        index: {unique: true}
      },
      messages: [
      {
        title: {type: String, required: true},
        msg: {type: String, required: true}
      }]
    }, {
        collection: &#39;contacts&#39;,
        safe: true
    });

and trying to update the model by doing this:

    Contact.findById(id, function(err, info) {
        if (err) return res.send(&quot;contact create error: &quot; + err);
    
        // add the message to the contacts messages
        Contact.update({_id: info._id}, {$push: {&quot;messages&quot;: {title: title, msg: msg}}}, function(err, numAffected, rawResponse) {
          if (err) return res.send(&quot;contact addMsg error: &quot; + err);
          console.log(&#39;The number of updated documents was %d&#39;, numAffected);
          console.log(&#39;The raw response from Mongo was &#39;, rawResponse);
    
        });
      });

I&#39;m I not declaring the `messages` to take an array of objects?  
**ERROR:** MongoError: Cannot apply $push/$pushAll modifier to non-array

Any ideas?  

pushing object into array schema in Mongoose

Doc:

    {
       _id: 5150a1199fac0e6910000002,
       name: &#39;some name&#39;,
       items: [{
          id: 23,
          name: &#39;item name 23&#39;
       },{
          id: 24,
          name: &#39;item name 24&#39;
       }]
    }

Is there a way to pull a specific object from an array?  I.E. how do I pull the entire item object with id 23 from the items array.

I have tried:

    db.mycollection.update({&#39;_id&#39;: ObjectId(&quot;5150a1199fac0e6910000002&quot;)}, {$pull: {id: 23}});

However I am pretty sure that I am not using &#39;pull&#39; correctly.  From what I understand pull will pull a field from an array but not an object.

Any ideas how to pull the entire object out of the array.

As a bonus I am trying to do this in mongoose/nodejs, as well not sure if this type of thing is in the mongoose API but I could not find it.

MongoDB, remove object from array

Is there a way to update values in an object?

    {
      _id: 1,
      name: &#39;John Smith&#39;,
      items: [{
         id: 1,
         name: &#39;item 1&#39;,
         value: &#39;one&#39;
      },{
         id: 2,
         name: &#39;item 2&#39;,
         value: &#39;two&#39;
      }]
    }

Lets say I want to update the name and value items for item where id = 2;

I have tried the following w/ mongoose:

    var update = {name: &#39;updated item2&#39;, value: &#39;two updated&#39;};
    Person.update({&#39;items.id&#39;: 2}, {&#39;$set&#39;:  {&#39;items.$&#39;: update}}, function(err) { ...

Problem with this approach is that it updates/sets the entire object, therefore in this case I lose the id field.

Is there a better way in mongoose to set certain values in an array but leave other values alone?

I have also queried for just the Person:

    Person.find({...}, function(err, person) {
      person.items ..... // I might be able to search through all the items here and find item with id 2 then update the values I want and call person.save().
    });

What is the difference between id and _id in mongoose?

Ran into this (slightly annoying problem) I&#39;m trying to look up all records in a collection and not show (or show) a specific field (score). This is just an example and not reflective of my actual code, but the problem is always reproducible. The fields I am excluding are very large and I&#39;m merely trying to generate a menu of available records.

Commands like 

        players.find({},{score:1})
        players.find({},{score:0})

Always return every field, instead of triggering the exclude/include in mongodb. Am I worried about nothing, since the template potentially can control what data gets rendered to html? Still feels like the data is transferred to the client side regardless; and shows up in the console.

Meteor - collection.find() always returns all fields

How can I make a backup of my meteor mongo database?

I&#39;m starting with Meteor, and I&#39;d like to know how to list the installed packages.

`meteor list` would only list the available packages in the registry.

Edit: Since meteor 0.9.0.1 `meteor list` lists the available packages in the project.


Meteor: How to list the installed packages

I have a helper like

    Template.user_profile.helpers({
      user:function() {
         return Meteor.users.find({&#39;profile.front_name&#39;:Session.get(&#39;slug&#39;)}).fetch()[0];
      }
    });

I want to add a helper to the collection which could access the `user` helper and compare its `_id` with the current user `_id`, to tell whether the user is visiting its own profile.
I&#39;m using something pretty ugly:

    Template.user_profile._tmpl_data.helpers.user()

The final code:

    Template.user_profile.helpers({
      user:function() {
         return Meteor.users.find({&#39;profile.front_name&#39;:Session.get(&#39;userId&#39;)}).fetch()[0];
      },
      isCurrentUser: function() {
        return Template.user_profile._tmpl_data.helpers.user()._id === Meteor.userId();
      }
    });

Is there any better way to access another helper?
