Hi folks,
I''m using ruby-GD and Rails to dynamically generate and serve images,
as
follows:
require ''GD''
...
def image
g = GD::Image.new(100,100)
g.colorAllocate(255,255,255)
red = g.colorAllocate(255,0,0)
g.line(10,10,90,90,red)
@headers["Content-Type"] = "image/png"
render_text g.pngStr
end
This works just beautifully under ordinary CGI. However, FCGI complains
about having two "Content-Type" headers. There is only one in the
output
if run under CGI, so Apache must strip out the duplicate, but under FCGI
it crashes and returns 500 Infernal Server Error instead. Why is the
(presumably) text/html header not getting replaced?
Tim.

When I tried to recreate the original problem today, I couldn''t repeat it. The above worked, as did my original code. I don''t know what changed in the meantime, so I''m a little perplexed.

Hello,
I''ve got some troubles, when I''m reimplementing my first rails
application with tests. I got view, which normaly render on production
system. Code is clear I think:
code:
<%= form_tag({ :action => @target }) %>
<%= hidden_field "question", "id" %>
<h3>Text:</h3>
<%= text_area "question", "text", "cols"
=> 60 %>
<h3>Okruh:</h3>
<select name="question[area_id]">
<% options_for_select(get_areas, @question.area.id) %>
</select>
<input type="submit" value="Ulozit" />
</form>
It''s in the partial, so I can use this form for more views.
But the problem arise, when I''m trying to do functional tests. It
yields to:
stact_trace:
ActionView::TemplateError: wrong number of arguments (0 for 1)

Maybe I''m doing something wrong, but I can''t see any way how
to work
around. The worst thing is that it''s *only* in tests :-(.
Thanks for any help or suggestion.

I just found out, that if I comment out text_area method call everything works fine. Hope it helps, cause I can''t see any way how to solve it. Maybe it''s common punishment for doing something good (test driven development in this case:) Pepe On 14.11.2004, at 12:50, Josef Pospisil wrote:> Hello, > > I''ve got some troubles, when I''m reimplementing my first rails > application with tests.
