I’m pretty sure you can use the Rack::Request
object for passing request-scope variables:
# middleware:
def call(env)
request = Rack::Request.new(env) # no matter how many times you do 'new' you always get the same object
request[:foo] = 'bar'
@app.call(env)
end
# Controller:
def index
if params[:foo] == 'bar'
...
end
end
Alternatively, you can get at that “env
” object directly:
# middleware:
def call(env)
env['foo'] = 'bar'
@app.call(env)
end
# controller:
def index
if request.env['foo'] == 'bar'
...
end
end
