Changing filenames gives [ERROR] Missing field $posts$ in context for item archive.html

You still have a call to recentFirst l55.

You should write a recentFirst' based on chronologicalItems (something like
fmap reverse . chronologicalItems)

Hello all,
Noob question.
I'm trying to set up a site using Hakyll and I'm having a strange problem
with my attempts to move away from the convention of dates in filenames. I
was able to make Hakyll get the date field from the metadata rather than
[ERROR] Missing field $posts$ in context for item archive.html
when I rename a file in the posts directory from
2013-06-04-carpe-diem.markdown to carpe-diem.markdown. I can't find
anything in the documentation, or think of any reason, why changing the
filename should affect the posts field.
Can anyone shed some light on this? I've attached the entire site.hs file
for reference; it is little changed from the default generated by
hakyll-init. If it is more convenient, you can also view it at
http://hpaste.org/89317.
Thanks,
Nabil Hassein

I took Clement's suggestion, but I still get the same error. Perhaps I
should add that ghc --make site.hs compiles just fine; I get the error
I copy-pasted above then I try to run ./site build.

Ack, a typo in my previous message totally changes the meaning. I
meant:

I should add that ghc --make site.hs compiles just fine; I get the
error I copy-pasted above WHEN (corrected) I try to run ./site build.

I was trying to say that I compile first with no error, and then after
that, the error i posted is among the results of "./site build".

I feel like a fool, the parse function is very picky. I was trying to
debug why it wasn't
parsing 2015-11-8 and just failing, and I had removed the filenames, and
was trying all kinds of things from this thread, but it turns out that you
are required to have 2015-11-08.
See the difference?

I feel like the error message could maybe be more clear as to the error.

Hi,

Unfortunately I don't have a solution, but I'm having exactly the same
issue, so hoping someone could help us?

Thanks,

Your `dateCtx` seems weird. I don't know exactly how it behaves, but since
the date is not part of the filename anymore, the `getItemUTC` l.90 tries
to parse the `date` and `published` fields.

I can only guess that the default date field value "unknown date of
posting" of the `dateCtx` l.76 disrupts the `getItemUTC`, which then
disrupts the `forM` in the `withTime` function l.89.
Your post list would then be empty, and the `$posts$` field would not be
set, thus triggering the error.

There is a lot of speculation here, but it's late and I am on my gaming PC,
so no haskell :/

Hope this helps,
Julien

An additional note: running with `-v` gives a lot of extra info and
might help us figure out this issue.

Hey Jasper,

Just getting started with Hakyll. Looking good so far but I had a similar
problem to OP.

OP, after trying for a few hours, I can't seem to find why your code is not
working.

@Jasper, one problem I did find though is that dateField at least currently
doesn't actually support using the published or date metadata fields to get
the date. Reproduction steps are as follows:

1. Make example site.
2. Delete the date prefix in one of the markdown post's filename.
3. Add the follow lines below the title metadata
---
published: 2012-07-07
---
4. Try to rebuild the site. Will error with "missing field $date$ for item
posts/(whatever file you modified)"

I've added the bug to the issue tracker on GitHub.

Also, I would like a mention of this point in the tutorial. I'm all for
defaults over configuration but they should be mentioned. I would like this
mentioned in the tutorial especially because making new posts and new
fields based on posts are key elements in copying/extending tutorial
example.

I found the problem extremely frustrating because the problem has nothing
to do with code or templates. Just the file name. Also the
examples/documentation often say something like "posts/foo.markdown" which
obviously will not just drop into the example site.

Thank you for Hakyll though! I'm really enjoying learning more about the
system but I felt that this was a surprise gotcha that really frustrated me.

Ward regards,

David Flicker

Hey David,

I can't reproduce this issue with the latest Hakyll -- it works fine
for me. I moved a post to `posts/spqr.markdown` and changed the
contents of that file to:

---
title: S.P.Q.R.
published: 2012-07-07
---

Mauris in lorem nisl...

Am I missing something? What version of Hakyll are you using?

Hey Jasper,

I was being extremely stupid and not realizing that to add more metadata
this format should be used:
---
title: Foo
published:2012-05-05
more_metadata: Bar
---

I was doing this:
---
title: Foo
---

Thanks for the help!
