catchsomeair.us - Unable to connect to mongolab, Getting MongoError: auth failed - Stack Overflow
Another item to note is that mLab runs the MongoDB process with the “auth” mode marketplace: (1) The convenience of a single billing and vendor relationship; website (e.g., for Heroku, catchsomeair.us mongolab). Mongo::AuthenticationError: Failed to authenticate user 'heroku_app' on db @app/gems/mongo/lib/mongo/functional/catchsomeair.us You'll set up the app, migrate it to mLab, then start a Heroku instance and First, you set up a MongoDB database (on mLab, or equivalent) and let Parse .. Authentication works sort of like a password and in our case, the.
A sample user, johndoe is created with an age of 25, and then is saved to the MongoDB database. Querying Fetching the list of power users from the collection is done with the capable find method. The query syntax for Mongoose is a chain of conditions to be matched. The query is executed by invoking the. Below is the generic form for the query. Other query conditions can be applied to filter specific fields, sort and paginate.
The first query is the empty object which matches against all documents and is immediately executed. The second query describes a name. Below the query is the empty object which matches against all documents. To query based on conditions use the query syntax for Mongoose which is a chain of properties to be matched, typically ending in.MEAN Stack App Part 5 - Using MLab for DB & Deploying app to Heroku
This is a very flexible way to construct a query that is only executed when needed. You may override its assignment with your own identification scheme so long as the uniqueness property holds for that collection; however, we advise against doing so. This will use single-sign-on to authenticate you to the MongoLab interface where you can click on the PowerUsers collection and see an editable web UI view of the document.
For larger collections, the saved queries can also be very helpful in debugging and developing an application. Summary In this tutorial you created a Node. For next steps you can visit the links below for more information about each component.
Parse strongly recommends you to migrate to Parse Server as soon as possible. In the diagram you see a dotted line, which indicates an intermediary state in which you still communicate with the Parse back-end, but in which Parse communicates with your self-hosted MongoDB database.
This allows for a two-step migration: In either case, your app will point to a single database. While the migration is taking place, Parse will keep track of additions and will sync them after the initial migration completes.
Both steps are documented in this code guide. You can read more on this in the conclusion of this code guide. Learn More Start for Free 1.
The app is part of a code guide originally published on AppCoda. The Paws app is a minimal Instagram-clone that shows pictures of cats in a vertical timeline. Users can upvote a cat picture by double-tapping on its image. Download the ZIP and unzip it in a convenient location. If you have Git installed, you can of course also clone the project.

In the same root directory, type this on the command-line: Make sure you press the Enter key after you type in a Terminal command. CocoaPods will now read the Podfile, which contains a reference to pods Parse and ParseUI, and attempts to download their latest versions. It also builds the pods and adds them to our Paws. You can use Finder to locate the file, or open Xcode and then open the right workspace.
First, download the following file: It contains the data for the app, including the URLs of the cat photos, photo credit information, and the names of the cats. Second, unzip the file in a convenient location. Next up, go to parse.

Skip ahead of part 2, creating a MongoDB database with mLab, and follow the special instructions on importing the app data in mLab. On your Parse dashboardclick the Create a new app button. Parse Dashboard Click on the This will take you to the previous version of the Parse Dashboard UI. Your screen should now look like this: Old Parse Core Next, do this: First, click the Import button. A dialog box appears. Locate the data file you previously unzipped. Make sure to upload the.

Then, once the file is uploaded, choose Custom for Collection Type and name the collection Cat. Finally, click Finish Import. Locate the following two text strings. Then, replace the first Then, replace the second The first part of the code block now looks like this: Finally, run the app by pressing Command-R or by clicking on the Run button at the top-left of Xcode.
The app should compile and run, resulting in a screen similar to this: You publish the beautiful Paws app on the App Store and amass a large number of monthly active users.
You sit back and enjoy your app with its convenient Parse back-end. I mean, you had two certainties in your life: We saw in the overview at the top of this article that Parse will now run on two new services: Then, log into your new account. Sign up, wait for the verification email to arrive in your inbox, click the link, then get back to the mLab dashboard.
On the dashboard, click the Create New button. On the page Create new subscription page that appears, do the following: First, choose Amazon Web Services as cloud provider.
Then, select the Single Node tab and choose the Sandbox option. Then, name the database paws. Finally, click Create new MongoDB deployment. The new database is created. You can of course choose different MongoDB options depending on the requirements of your app. Parse recommends to 10x the size of your Parse data when creating a new MongoDB database. Click on the database to open its detail screen. Database details First, click the Users tab.
Then, click Add database user. Then, in the dialog that appears, input paws as username and input a strong password, then click Create.
Make sure to leave the Make read-only checkbox unticked. Make sure you note the paws username and its password somewhere safe. You will need it later.
The result should look something like this: Then, paste the mongodb: This concludes the first part of the migration. At this point, you need to have the Paws source code set up, have created a mLab account, created the paws MongoDB database, and created the paws database user.
Before you can install the tools, you need to install Homebrew. One of those tools is MongoDB. Make sure the resulting unzipped directory is called paws. Next, go to your mLab dashboard, open the paws database and click the Tools tab. Find the first one, right below Import database.
The tool restores a MongoDB database, based on parameters, essentially entering data into the empty database you created previously. Before you can use the command, you need to configure the parameters. Then, edit the parameters one by one: The entire command now looks similar to this: The result in Terminal looks something like this: Because the steps involved are quite complex, this is a high-level recap: Get a mLab account and log in.
When it completes, verify the data and complete the migration.
Go to the Tools tab of your database in mLab. Note the Import database CLI command, copy it to a text file, and change its parameters to reflect your values username, password and directory.
Paste the mongorestore command from the text file in Terminal and execute the command. You read in the overview that Parse is a done-for-you, managed and scalable Platform-as-a-Service. If you would draw a line, put Parse on the right, and a bare-metal or VPS server on the left, you can place Heroku somewhere in the middle. With Heroku you create containerized instances of your app. One container for every Parse Server app. Before you have access to these CLI tools, you need to install them.
In order to install, do this: First, go to toolbelt. Then, once the download finishes, open the PKG file and follow the installation instructions. You can find it on GitHub: You now need to download the source code on your local computer. First, open Terminal and cd to your home directory: Then, clone the parse-server-example with Git in the current directory.
