Expo Publish How to let others join - expo

I would like to ask How can my teammates join my project after i publish the project. There are QR code but if they didn't log in to my account they could not open it. Are there any ways for my teammates to join me without logging in to my account or they must log in to my account in order to pre-view or contribute the project? Thank you.

Not able to list Bigquery projects from Data Studio Connection

From Data Studio, I am not able to list any Big Query projects. Not even Public projects. I have access to Big Query Tables and projects, but once I log in through Data Studio and try to add a data source, it's showing all blank, including custom queries, etc.
I also faced the same situation and I hope this helps someone else with this confusion. I'm assuming that this could be the solution to this question too. (Do let me know)
When you are trying to add a BigQuery connection to Data Studio, you need to have a Google Project because BigQuery is a paid service. The querying in BigQuery incurs a cost. A project with billing enabled, is not a must for you to load the Datasets in the above screenshot.
Follow these steps to get this issue fixed.
Check the email address you have used to connect to Data Studio. You can click on the avatar on the top right corner. (If this is wrong, simply switch to the correct email.)
Check whether Google Cloud Console is enabled for the above-selected email.
Check whether you have a project in the Cloud Console. Make sure there is a project to be used when creating a BigQuery connection from Data Studio.
With this, your view should show the projects linked with your Google Cloud Console email address.
If the above doesn't work..
Do a refresh of the page and see
If not, create a support ticket or Ask the Data Studio Community.

Flows Disappeared from Project

I've been using Dataprep for months, and have a lot of different flows built in one of my projects. I was working with it this morning, but now when I log in, the project in Dataprep is blank, like I'm a brand new user. I'm starting to panic because months of work has vanished! Does anyone have any suggestions on what to do?
Things I've tried without success:
I switched into a different project and I can see that project's
flows listed.
Logged out/in
restarted browser
Thank you for your help, you are correct. It turns out we received an email from google with the subject "[Action Required] Please migrate off JSON-RPC and Global HTTP Batch Endpoints" (specifically storage#v1). We were not using this API with the solutions we developed within this project, so one of our developers deactivated it. It showed the affected dependencies, which included the Dataflow API. DataPrep was not disabled, nor did it need to be reenabled before accessing it again...it just lost it's metadata like both Ali T and James commented.
Google Cloud Support recommends exporting the recipes and flows (manually I believe) as the best way to prevent DataPrep working file loss in the future.

Unknown error creating a project

I just came back to google's cloud platform and tools to work on a new project after not having touched my account for 9 months or so. The account has billing information. I just accepted the $300, 2 month trial on my account. Now, when I attempt to create new projects (in any and every way I have tried), I get a notification that says "Unknown error." The notification also provides a 'RETRY' option, which produces a new notification for the same error.
For me, the error was occurring because I was using my school email, which is technically a Google email, but maybe the school doesn't subscribe to all of Google's features or something. I logged in with my regular gmail account, and I was able to create a new project.
Ok, so the issue has to do with the project name or id. I appear to be able to create projects, just not using the names I would prefer as there is something about having the string '-dot-' in the name or id that throws an unknown error. I'll have to find the best way to contact google for help with specific bugs. In this case the name I want to use is 'mywebsite-dot-com' and that auto-generates a project id that is identical ('mywebsite-dot-com').
Update: Google support did respond and let me know that '-dot-' is indeed a hidden keyword and cannot be used in the project ID.

Anyone know if there is a Django auditing lib to track user/record activities?

I need add a auditing log to my system, so all changes on some module records be saved and be used for auditing purpose, this is a system to create and manage Raffle.
I am looking for a existing lib before I try to create one myself.
Thanks

Is it better to pull files from remote locations or grant users FTP access to my system?

I need to setup a process to update a database table with user supplied CSV-data (running Coldfusion 8/MySQL 5.0.88).
I'm not sure about the best way to do this.
Should I give users FTP-access to my system, generate a directory for every user and upload files from there, or should I pick files up from external locations, so the user has to setup an FTP folder my system can access. I'm sort of leaning towards the 2nd way and wanted to set this up using cfschedule and cfftp, but I'm not sure this is the best way to go forward. Security wise, I'm mor inclined to have users specify an FTP location, from where I pull, rather than handing out and maintaing FTP folders for every user.
Question:
Which approach is better both in terms of security and automation?
Thanks for input!
I wouldn't use either approach. I would give the users a web page to upload their csv files. The cf page that accepts the files would place them into a specific folder and make sure they have unique filenames. The cffile tag will help you with that.
The scheduled job would start with a cfdirectory tag on the target folder. This creates a query object. Loop through it and do what you have to do with each file.
Remember to check for the correct file extension. Then look at the first line of the file to ensure it matches the expected format.
Once you have finished processing the file, do something with it so that you don't process it again on the next scheduled job.
Setting up a custom FTP server is certainly a possibility, since you are able to create users, and give them privileges (automated). It is also secure.
But I don't know the best place to start if you don't have any experience with setting up a FTP server.
Try https://www.dropbox.com/
a.)Create a dropbox account,send invites to your users/clients.
b.)You can upload files/folders into dropbox,your clients/users can access it from their
dropbox account/dropbox desktop app..
c.)Your users/clients can upload files/folders and you can access it from your dropbox
website account/desktop app.
Dropbox is rank 1 software, better in security and automation.
