My app has started throwing errors when I try to save a particular class to the database. I'm not sure exactly what caused this to start happening - I've been having all kinds of database issues for the last few days.... In any case, my model seems to be working fine (it is properly calculating all of the before_save values), but then it tries to save to the database and blows up. SQL (0.8ms) INSERT INTO "portfolios" ("correlation_matrix", "created_at", "data", "mean_return", "std_dev", "updated_at", "weights") VALUES ($1, $2, $3, $4, $5, $6, $7) RETURNING "id" [["correlation_matrix", "--- \n-

How to fix the YAML syntax error: did not find expected '-' indicator while parsing a block?

I have some code written in my .travis.yml written for a Python library. Using lint.travis-ci.org , I came to know that there is some indentation problem in my YAML file. Here is the part which the error points to install: - if [[ "${TEST_PY3}" == "false" ]]; then pip install Cython; python setup.py build; # To build networkx-metis mkdir core; # For the installation of networkx core cd core; git clone https://github.com/orkohunter/networkx.git; cd networkx/; git checkout addons; python setup.py install; cd ..; fi Where am I wrong? The error says syntax error: (<unknown>): did not find expected

Python relative import causes SyntaxError exception

阅读更多关于 Python relative import causes SyntaxError exception

According to the python docs , relative importing and intrapackage referencing has been supported since python 2.5. I am currently running Python 2.7.3. So, I tried to implement this in my own package in order to use it for simpler importing. I was surprised to find it threw a SyntaxError exception at me, and I was hoping someone could help lead the way to the cause. I setup a test directory for testing: tester ├── __init__.py ├── first_level.py └── sub ├── __init__.py └── second_level.py Both __init__.py modules are empty. The other modules are: # first_level.py print "This is the first level

Incrementing Multiple Genvars in Verilog Generate Statement

阅读更多关于 Incrementing Multiple Genvars in Verilog Generate Statement

I'm trying to create a multi-stage comparator in verilog and I can't figure out how to increment multiple genvars in a single generate loop. I'm trying the following: genvar i,j; //Level 1 generate j=0; for (i=0;i<128;i=i+1) begin: level1Comp assign ci1[i] = minw(tc[j],tc[j+1]); j = j+2; end endgenerate And getting the following error: Error-[SE] Syntax error Following verilog source has syntax error : "encoder.v", 322: token is '=' j=0; Anyone know how to increment multiple genvars in the same generate statement? Or at least get equivalent functionality? Assuming that ci1 has half the depth

Only at the checkout and on individual product pages I am getting the following error in the console log: VM35594:1 Uncaught SyntaxError: Unexpected token u in JSON at position 0 at JSON.parse (<anonymous>) at run (layout.min.js:9) at app.min.js:1 at main.min.js:2 at Object.execCb (require.min.js:112) at Module.check (require.min.js:56) at Module.<anonymous> (require.min.js:72) at require.min.js:11 at require.min.js:74 at each (require.min.js:3) I am using a one page checkout extension, but when I disable that the error still shows. I thought it might had something to do with the reviews on

SYNTAX_ERR: DOM Exception 12 - Hmmm

阅读更多关于 SYNTAX_ERR: DOM Exception 12 - Hmmm

I have been working on a small slideshow / public display for a client that uses HTML5 Rock's Slideshow code . I have run into a DOM Exception 12 - a syntax error that is supposedly related to CSS selectors - while monkeying around with it... but I can't trace it back to any changes I made in the code. I am thinking it might be something that was uncovered as I added features. I have traced it down to this object (live version here ): var SlideShow = function(slides) { this._slides = (slides || []).map(function(el, idx) { return new Slide(el, idx); }); var h = window.location.hash; try { this

Syntax error with std::numeric_limits::max

I have class struct definition as follows: #include <limits> struct heapStatsFilters { heapStatsFilters(size_t minValue_ = 0, size_t maxValue_ = std::numeric_limits<size_t>::max()) { minMax[0] = minValue_; minMax[1] = maxValue_; } size_t minMax[2]; }; The problem is that I cannot use 'std::numeric_limits::max()' and the compiler says: Error 8 error C2059: syntax error : '::' Error 7 error C2589: '(' : illegal token on right side of '::' The compiler which I am using is Visual C++ 11 (2012) Your problem is caused by the <Windows.h> header file that includes macro definitions named max and min :

C error: Expected expression before int

阅读更多关于 C error: Expected expression before int

When I tried the following code I get the error mentioned. if(a==1) int b =10; But the following is syntactically correct if(a==1) { int b = 10; } Why is this? sheu This is actually a fairly interesting question. It's not as simple as it looks at first. For reference, I'm going to be basing this off of the latest C11 language grammar defined in N1570 I guess the counter-intuitive part of the question is: if this is correct C: if (a == 1) { int b = 10; } then why is this not also correct C? if (a == 1) int b = 10; I mean, a one-line conditional if statement should be fine either with or without

Why is whitespace sometimes needed around metacharacters?

A few months ago I tattooed a fork bomb on my arm, and I skipped the whitespaces, because I think it looks nicer without them. But to my dismay, sometimes (not always) when I run it in a shell it doesn't start a fork bomb, but it just gives a syntax error. bash: syntax error near unexpected token `{:' Yesterday it happened when I tried to run it in a friend's Bash shell, and then I added the whitespace and it suddenly worked, :(){ :|:& };: instead of :(){:|:&};: Does the whitespace matter; have I tattooed a syntax error on my arm?! It seems to always work in zsh , but not in Bash. A related
