Hi @mistercrunch this viz will be quite good for our project. It will give us lot of possibilities to create a rich Welcome dashboards for the user.
It will be great if we can use Jinja2 templates and query a datasource.
Using Jinja2 templates:
In my case I'm using existing `BaseTemplateProcessor`
`from superset.jinja_context import get_template_processor`
````
class MarkupViz(BaseViz):
"""Use html or markdown to create a free form widget"""
viz_type = "markup"
verbose_name = _("Markup")
is_timeseries = False
def query_obj(self):
return None
def get_df(self, query_obj=None):
return None
def get_code(self):
code = self.form_data.get("code", "")
processor = get_template_processor(self.datasource.database)
return processor.process_template(code)
def get_data(self, df):
markup_type = self.form_data.get("markup_type")
code = self.get_code()
if markup_type == "markdown":
code = markdown(code, extensions=['tables'])
return dict(html=code, theme_css=get_css_manifest_files("theme"))
````
Let me know if this is something good/NTH in order to create a PR.
