[WIP] Setcontent for front

[stryxx]

Checklist copied from #116. API won't be 100% the same, but functionality should be kept.

Basic

• {contenttype}
• {contenttype}/first/{number}
• {contenttype}/last/{number}
• {contenttype}/random/{number}
• random is not going to work with Doctrine ORM queries, see answer on Stack Oveflow for info.
• warning An alternative is to make a special Twig function/filter to handle random records.
• Random should be refactored for better performance.

{contenttype}/{id} - it cannot be supported because id is not unique for every of contenttype. id is unique globally, so it not possible to get correct contenttype by id.

• {contenttype}/{slug}

WHERE

• {key}: {value}

• {key}: {operator}{value} where operator is one of % < <= =

  warning Currently the operations will not work for numbers/dates/etc. because of JSON-encoded values.

WHERE advanced

• {key}: {value1} || {value2} or {key}: {value1} && {value2}
• "{key1} ||| {key2}": "{value1} ||| {value2}"
• {key}: 'now' and other special datetime selectors (e.g. now, today, yesterday, last year, next thursday).

Special

• limit {number}

• orderby {field} or orderby -{field}

  warning This works for fields that have only a single value (think of it as a column)

• Multiple sortorders (comma-separated)

• returnsingle

• printquery - I'm not sure if we should have this option

  warning Currently shows DQL. Let's see if we can show a runnable query instead.

Advanced

Pagination and Search are not implemented yet.

• allowpaging
• {contenttype}/search/{num} where filter: {term}
• {ct1},{ct2},{ctN}/search/{num} where filter: {term}

Misc

• Implementations for locales, taxonomies and relationships.
• Proper integration with Config + ContentType data (such as max results per page).

New feature

• Add getcontent function for twig allows to get content by direct GraphQL query.

Good to see you back in action on this! 👍

[stryxx]

I happy too ;) I'm back with full bag of good (imo :P) ideas ;)

[bobdenotter]

I haven't commented much on this, but that doesn't mean i'm keeping an eye on it. ;-)

Just let me know when you think it's done, or ready for a second pair of eyes. 👍

Thanks Bob, I'm going to let you know ;) It comes to the end ;)

This PR has been lingering for two and a half years now. I think it's time to close it. 😔
