A mechanism in the metadata.json format for adding custom CSS and JS urls.
Create a metadata.json file that looks like this:
{
"extra_css_urls": [
"https://simonwillison.net/static/css/all.bf8cd891642c.css"
],
"extra_js_urls": [
"https://code.jquery.com/jquery-3.2.1.slim.min.js"
]
}
Then start datasette like this:
datasette mydb.db --metadata=metadata.json
The CSS and JavaScript files will be linked in the <head> of every page.
You can also specify a SRI (subresource integrity hash) for these assets:
{
"extra_css_urls": [
{
"url": "https://simonwillison.net/static/css/all.bf8cd891642c.css",
"sri": "sha384-9qIZekWUyjCyDIf2YK1FRoKiPJq4PHt6tp/ulnuuyRBvazd0hG7pWbE99zvwSznI"
}
],
"extra_js_urls": [
{
"url": "https://code.jquery.com/jquery-3.2.1.slim.min.js",
"sri": "sha256-k2WSCIexGzOj3Euiig+TlR8gA0EmPjuc79OEeY5L45g="
}
]
}
Modern browsers will only execute the stylsheet or JavaScript if the SRI hash
matches the content served. You can generate hashes using www.srihash.org
Rows page for rows that linked to the same table in more
than one columns were display incorrectly. Fixed that and added a test.
Also introduced /db/table/row-pk.json?_extras=foreign_key_tables
This is used by the new unit test, but is the first example of a new
?_extras=comma-separated-list pattern I am introducing.
This:
?_filter_column_1=name&_filter_op_1=contains&_filter_value_1=hello
&_filter_column_2=age&_filter_op_2=gte&_filter_value_2=12
Now redirects to this:
?name__contains=hello&age__gte=12
This is needed for the filter editing interface, refs #86
URL shortcut for counting rows grouped by one or more columns.
?_group_count=column1&_group_count=column2 works as well.
SQL generated looks like this:
select "qSpecies", count(*) as "count"
from Street_Tree_List
group by "qSpecies"
order by "count" desc limit 100
Or for two columns like this:
select "qSpecies", "qSiteInfo", count(*) as "count"
from Street_Tree_List
group by "qSpecies", "qSiteInfo"
order by "count" desc limit 100
Refs #44
Still todo: clean up code a bunch (it currently fakes being a 'view'), get
foreign key expansion working.
if filter_op contains a __ the value is set to the right hand side.
e.g.
?_filter_column=col&_filter_op=isnull__1&_filter_value=x
Redirects to:
?col__isnull=1
Refs #86
Part of implementing the filters UI (refs #86) - the following:
/trees/Trees?_filter_column=SiteOrder&_filter_op=gt&_filter_value=2
Now redirects to this;
/trees/Trees?SiteOrder__gt=2
The `datasette publish` and `datasette package` commands both now accept an
optional `--build` argument. If provided, this can be used to specify a branch
published to GitHub that should be built into the container.
This makes it easier to test code that has not yet been officially released to
PyPI, e.g.:
datasette publish now mydb.db --branch=master
If a table has foreign key columns, and those foreign key tables have
label_columns, the TableView will now query those other tables for the
corresponding values and display those values as links in the corresponding
table cells.
label_columns are currently detected by the inspect() function, which looks
for any table that has just two columns - an ID column and one other - and
sets the label_column to be that second non-ID column.
