## Import
|
|
|
|
Use the `mongoimport` command/tool to import the `factbook.json` documents.
|
|
For example, to import the country profile of Austria (that is, `europe/au.json`) use:
|
|
|
|
```
|
|
$ mongoimport --db world --collection factbook --file europe/au.json
|
|
```
|
|
|
|
To import all documents use a shell script. Example `import.sh`:
|
|
|
|
``` bash
|
|
#!/bin/bash
|
|
|
|
MONGOIMPORT = mongoimport
|
|
SOURCE = . # assume working folder (as root)
|
|
|
|
function import_file {
|
|
echo " importing >${1}<..."
|
|
${MONGOIMPORT} --db world --collection factbook --file ${1}
|
|
}
|
|
|
|
function import_region {
|
|
for file in ${SOURCE}/$1/*.json
|
|
do
|
|
import_file ${file}
|
|
done
|
|
}
|
|
|
|
import_region africa
|
|
import_region antarctica
|
|
import_region australia-oceania
|
|
import_region central-america-n-caribbean
|
|
import_region central-asia
|
|
import_region east-n-southeast-asia
|
|
import_region europe
|
|
import_region middle-east
|
|
import_region north-america
|
|
import_region oceans
|
|
import_region south-america
|
|
import_region south-asia
|
|
import_region world
|
|
```
|
|
|
|
To check up if all country profiles got imported use a query in the mongo shell e.g.:
|
|
|
|
```
|
|
> use world
|
|
switched to db world
|
|
> db.factbook.count()
|
|
261
|
|
```
