问题描述
我的模特地点由以下部分组成:
我使用的是Google-Maps-for-Rails创业板,我正在尝试显示圈子。 >
- 经度
- 纬度
-
我没有问题显示标记:
pre>#控制器:@markers = Place.all.to_gmaps4rails
gmaps(markers=> {data=> @markers})
不幸的是,它不包含:radius => ..
我也知道可以显示如下的圆圈:
gmaps(
circles=> {data=>'[
{ 经度:-122.214897,latitude:37.772323,radius:1000000}
]',
})
有没有办法在标记哈希中包含radius属性?像:
gmaps(circles=> {data=> @markers})
可能是这样的:
Place.all.each | place | place.merge!(:radius => 1000)...
可以,但我认为可能有更好的解决方案
解决方案标记和圆圈背后的逻辑真的不同。
在您的控制器中
@markers = Place.all.to_gmaps4rails
@circles = Place。 all.map {| p | {:longitude => p.longitude,:latitude => p.latitude,:半径=>
$ p
$ b $ p
<%= gmaps({markers=> {data=> @markers},
circles=> { data=> @circles}
})%>如果您不需要infowindow
或其他功能,您可以简单地执行:
在您的控制器中
@circles = Place.all.map {| p | {:longitude => p.longitude,:latitude => p.latitude,:半径=>
$ p
$ b $ p
<%= gmaps({markers=> {data=> @circles},
circles=> { data=> @circles}
})%>
i am using the Google-Maps-for-Rails gem and I am now trying to display circles.
My Model "Place" consists of:
- longitude
- latitude
- radius
- etc
I have no problem to display markers:
# Controller: @markers = Place.all.to_gmaps4rails gmaps("markers" => {"data" => @markers})
Unfortunately it doens't include :radius => ..I also know that circles can be displayed like:
gmaps( "circles" => { "data" => '[ {"longitude": -122.214897, "latitude": 37.772323, "radius":1000000} ]', })
Is there any way to include the radius attribute in the markers hash ? Like:
gmaps("circles" => { "data" => @markers })
Probably something like:
Place.all.each |place| place.merge!(:radius => 1000) ...
would do, but I think there may be a nicer solution
解决方案The logic behind markers and circles is really different.
In your controller
@markers = Place.all.to_gmaps4rails @circles = Place.all.map{|p| {:longitude => p.longitude, :latitude => p.latitude, :radius => p.radius}}.to_json
In your view:
<%= gmaps({ "markers" => {"data" => @markers}, "circles" => {"data" => @circles} }) %>
Or if you don't need
infowindow
or other features, you could simply do:In your controller
@circles = Place.all.map{|p| {:longitude => p.longitude, :latitude => p.latitude, :radius => p.radius}}.to_json
In your view:
<%= gmaps({ "markers" => {"data" => @circles}, "circles" => {"data" => @circles} }) %>
