Small extension for Flask to make using Google Maps easy
Project description
# Flask Google Maps
Easy to use Google Maps in your Flask application
### requires
- Jinja
- Flask
- A google api key (optional I guess)
### Installation
```pip install flask-googlemaps```
or
```bash
git clone https://github.com/rochacbruno/Flask-GoogleMaps
cd Flask-GoogleMaps
python setup.py install
```
### How it works
Flask-GoogleMaps includes some global functions and template filters in your Jinja environment, also it allows you to use the Map in views if needed.
#### registering
in your app
```python
from flask import Flask
from flask_googlemaps import GoogleMaps
app = Flask(__name__)
GoogleMaps(app)
```
In template
```html
{{googlemap("my_awesome_map", lat=0.23234234, lng=-0.234234234, markers=[(0.12, -0.45345), ...])}}
```
That's it! now you have some template filters and functions to use, more details in examples and screenshot below.
### Usage
- You can create the map in the view and then send to the template context
- you can use the template functions and filters directly
#### 1. View
```python
from flask import Flask, render_template
from flask_googlemaps import GoogleMaps
from flask_googlemaps import Map
app = Flask(__name__, template_folder=".")
GoogleMaps(app)
@app.route("/")
def mapview():
# creating a map in the view
mymap = Map(
identifier="view-side",
lat=37.4419,
lng=-122.1419,
markers=[(37.4419, -122.1419)]
)
sndmap = Map(
identifier="sndmap",
lat=37.4419,
lng=-122.1419,
markers={'http://maps.google.com/mapfiles/ms/icons/green-dot.png':[(37.4419, -122.1419)],
'http://maps.google.com/mapfiles/ms/icons/blue-dot.png':[(37.4300, -122.1400)]}
)
return render_template('example.html', mymap=mymap, sndmap=sndmap)
if __name__ == "__main__":
app.run(debug=True)
```
##### `Map()` Parameters:
- **lat**: The latitude coordinate for centering the map.
- **lng**: The longitutde coordinate for centering the map.
- **zoom**: The zoom level. Defaults to `13`.
- **maptype**: The map type - `ROADMAP`, `SATELLITE`, `HYBRID`, `TERRAIN`. Defaults to `ROADMAP`.
- **markers**: Markers array. Defaults to `None`.
- or **markers**: Markers dictionary with icon urls as keys and markers array as values.
- **varname**: The instance variable name.
- **style**: A string containing CSS styles. Defaults to `"height:300px;width:300px;margin:0;"`.
- **identifier**: The CSS ID selector name.
- **cls**: The CSS Class selector name. Defaults to `"map"`.
#### 2. Template
```html
<!DOCTYPE html>
<html>
<head>
{{"decoupled-map"|googlemap_js(37.4419, -122.1419, markers=[(37.4419, -122.1419)])}}
{{mymap.js}}
{{sndmap.js}}
</head>
<body>
<h1>Flask Google Maps Example</h1>
<h2> Template function centered, no marker </h2>
{{googlemap("simple-map", 37.4419, -122.1419)}}
<h2> Template filter decoupled with single marker </h2>
{{"decoupled-map"|googlemap_html(37.4419, -122.1419)}}
<h2> Template function with multiple markers </h2>
{% with map=googlemap_obj("another-map", 37.4419, -122.1419, markers=[(37.4419, -122.1419), (37.4300, -122.1400)]) %}
{{map.html}}
{{map.js}}
{% endwith %}
<h2> First map generated in view</h2>
{{mymap.html}}
<h2> Second map generated in view</h2>
<h3> Example for different icons in multiple markers</h3>
{{sndmap.html}}
</body>
