Export from Wekan Sandstorm grain .zip file
This is useful for example if you get Board not found error
Using Ubuntu 18.04 or Mint 19.1 or Ubuntu for Windows Subsystem for Linux:
sudo apt-get install zip unzip p7zip-full wget
cd
wget https://releases.wekan.team/meteor-repair.7z
7z x meteor-repair.7z
https://docs.mongodb.com/v3.2/tutorial/install-mongodb-on-ubuntu/
Use Sandstorm arrow down button to download Wekan grain in .zip file to your home directory.
unzip "YOUR-GRAIN-NAME-HERE.zip"
.meteor/packages/meteor-tool/1.6.0_1/mt-os.linux.x86_64/dev_bundle/mongodb/bin/mongod --dbpath "./YOUR-GRAIN-NAME-HERE/data/wiredTigerDb" --repair
Currently Wekan uses Meteor 1.6.0.1. In .meteor/packages/meteor-tool/ directory is also some 1.8.x version for upcoming Wekan version using Meteor 1.8.x. This .meteor directory has been generated by installing meteor from www.meteor.com and then upgrading some existing or new app with for example meteor update --release 1.6.0.1 so that correct version of Meteor is downloaded.
sudo systemctl stop mongod
sudo su
cd /var/lib
mv mongodb mongodb-original
cp -pR "/home/YOUR-USERNAME/YOUR-GRAIN-NAME-HERE/data/wiredTigerDb" .
mv wiredTigerDb mongodb
chown mongodb:mongodb mongodb -R
systemctl start mongod
exit
mongo
show dbs
use meteor
show collections
db.users.find();
exit
mongodump --db meteor
Save this to dump-json.sh and then chmod +x dump-json.sh && ./dump.sh meteor filesdir
Script is originally from this Rocket.Chat issue
#!/bin/bash
if [ ! $1 ]; then
echo " Example of use: $0 database_name [dir_to_store]"
exit 1
fi
db=$1
out_dir=$2
if [ ! $out_dir ]; then
out_dir="./"
else
mkdir -p $out_dir
fi
tmp_file="fadlfhsdofheinwvw.js"
echo "print('_ ' + db.getCollectionNames())" > $tmp_file
cols=`mongo $db $tmp_file | grep '_' | awk '{print $2}' | tr ',' ' '`
for c in $cols
do
mongoexport -d $db -c $c -o "$out_dir/exp_${db}_${c}.json"
done
rm $tmp_file
It's also possible to restore JSON files like described at stackoverflow this way, but because userIDs etc can be different, there is no mapping to other users, so you may need to change JSON files some way:
for file in *.json; do c=${file#*exp_yourdbname_}; c=${c%.json}; mongoimport --db yourdbname --collection "${c}" --file "${file}"; done
Download NoSQLBooster GUI webpage
If you download AppImage for Linux, run it with:
chmod +x nosqlbooster4mongo*.AppImage
./nosqlbooster... (full filename here)
It can install NoSQLbooster to Linux Menu/Programming/NoSQLBooster for MongoDB.
With it connect to localhost:27017
Double click cfs_gridfs.attachments.files and right click filename and Download file.
a) Restore data to Standalone Wekan Snap
b) Figure out how to make Sandstorm grain .zip file
In .zip file database files are in directory data/wiredTigerDb/
In Wekan Snap, database files are in directory /var/snap/wekan/common - if you have other data there, rename common directory to other name first.
In Snap:
sudo chown root:root /var/snap/wekan/common -R
In Snap:
sudo snap start wekan.mongodb
Try does Standalone Wekan work with that database
sudo snap start wekan.mongodb
sudo snap start wekan.wekan
or both wekan and database at once
sudo snap start wekan
Wekan Snap: Connect it to address localhost:27019
Wekan Docker: If you have MongoDB exposed to outside Docker, Connect with Robo3T to address localhost:27017. Otherwise you first need to copy files from wekan-db Docker container to outside of Docker container, and restore files to local separately installed MongoDB database v3.2.20 or newer
- On left, double click cards, checklists etc collections/tables to see their contents
- Currently default view to see is tree view. To see table view or JSON view, click small buttons above that white data area view display at near right border.
In Linux, you can install Hex Editor for example with command:
sudo apt install ghex
or
sudo yum install ghex
Then it's usually in Linux desktop at Menu / Development / GHex.
Or you can start it in command line by writing ghex
You can open files from your unzipped Wekan Sandstorm grain directory data/wiredTigerDb/ to see if there is still some data that is not yet overwritten with other data.
12.1 Compare databases of Sandstorm and Docker Wekan with mongo GUI https://nosqlbooster.com/
12.2 Create new user to Standalone Wekan
12.3 Copy new user bcrypt password structure created bcrypt encrypted password from Sandstorm to Docker wekan structure. It's at users collection/table. Also add isAdmin=true boolean.
12.4 Login
12.5 Here is info about script how to save all from MongoDB to .JSON textfiles https://forums.rocket.chat/t/big-issue-with-custom-javascript/261/4 and most likely how to get them back to mongodb so just copying all of those boards JSON files and restoring to MongoDB database would work and editing JSON files with any plain text editor. For big files you can try JEdit.
12.6 Here is how to backup and restore mongodb in docker, snap etc https://github.com/wekan/wekan/wiki/Backup
12.7 All Wekan Docker settings are in this textfile https://raw.githubusercontent.com/wekan/wekan/devel/docker-compose-build.yml
12.8 Database name in Sandstorm is meteor, and in docker is wekan, so here is how to restore with different database name https://stackoverflow.com/questions/36321899/mongorestore-to-a-different-database
