database from the version immediately before `0.3` to the `0.3` version of the
app.
**Always** make a backup of your database prior to running a migration on it.
If you upgrade through several versions at once, you should run all the
migrations scripts for all the intermediate versions, in the ascending order.
There are currently no automated way to handle the updates of the database

@ -56,11 +56,11 @@ If you want to make an `OR` condition, satisfying either one of the filters,
you should make two different API calls.
#### Commplex filtering
#### Complex filtering
You can also use more complex elaborations through the syntax
`filter[FIELD][OPERATION]=VALUE`. The available operations are `eq` (equal,
default operation), `ne` (not equal), `gt` (greater than), `ge` (greater or
`filter[FIELD][OPERATOR]=VALUE`. The available operators are `eq` (equal,
default operator), `ne` (not equal), `gt` (greater than), `ge` (greater or
equal), `lt` (lower than) and `le` (lower or equal). For instance,

```
> GET /api/v1/reports?filter[lat][gt]=LAT_MIN&filter[lat][lt]=LAT_MAX&filter[lng][gt]=LNG_MIN&filter[lng][lt]=LNG_MAX
```
All operators can have a trailing `?` to make them consider fields without
value as matching the condition as well. This means you can use something like
```
> /api/v1/reports?filter[expiration_datetime][gt?]=2018-10-18T09:06:38.538375
```
to get the all the reports with an expiration datetime in the future or no
expiration datetime, that is all currently active reports, assuming the
current datetime is `2018-10-18T09:06:38.538375`.
