help: ActionController::UnknownFormat in FooController#index

HI,

i have a couple of ‘seo’ routes, which are not responding well

eg:

match ‘whatever/in/:seoterm’ , as: 'seo_whatever

_in’ , :to => ‘foos#index’, via: [:get] , :mode=>{:x=>’ whatever

',:y=>1}

respond_to do |format|

format.html {

}

format.js {

}

format.json {

render :json => JSON::parse({:list => @… }

}

format.xml {

#render xml: @person.to_xml(include: @company)

render xml: @commutes.to_xml #(include: @company)

}

end

→ the only thing i see is that the brwoser comes as / , which shouldnt be the problem:

Started GET “/whatever/in/St.%20Peters” for 10.0.1.37 at 2018-03-05 12:09:39 -0500

Processing by FooController#index as

any ideas?

thx

What does that mean?

getting 406 due to rails giving me ActionController::UnknownFormat and i dont know why.

same routes(pattern) in a different controller work just fine. only difference is that the other one only does render, not repsond_to

Maybe because GET "/whatever/in/St.%20Peters" provides no information about the requested response format?

I'd think that would be a good clue...

so how can i pass this along? why is it not assuming html?

Because computers don't make assumptions? :grinning:

Why are you telling it to respond differently depending on the format and then *not providing a format*??

You really should have added one more line from the log here.

It was very likely looking for a :format => '%20Peters" because of the ‘.’ in the URL path.

Look at the output from rails routes to see the various ways that you might be routing to foos#index

Another way to fix this tends to “break” having multiple formats. You can add:

eg:

match ‘whatever/in/:seoterm’ , as: ‘seo_whatever _in’ , :to => ‘foos#index’, via: [:get] , :mode=>{:x=>’ whatever ',:y=>1}

, constraints: { seoterm: /.+/ }

so that :seoterm slurps all the remaining characters of the URL. This breaks the “implicit” (.:format) that gets added because the constraint will match the ‘.’ and everything after it leaving nothing to match the “optional” format.

you are correct. the space and or the period was the problem here.
